This is issue 869 and is required for several reasons: 1) to make Inishell more
similar to MeteoIO, Snowpack, etc 2) because Qt6 is moving to CMake in
replacement of qmake 3) because it will "easily" allow creating native packages
for several platforms.

Analogous to the currently loaded app name now the app path is also
available. Minor cleanup of an obsolete parameter.

Now in addition to doc:// we can link to dev://

The users will want to know where a link leads, now this is
displayed in the status bar temporarily.

- Implement issue 826:
  Replicator keys can now be empty in which case they will not be tied
  to any INI structure and can spawn arbitrary INI keys.
- Numbers now do not have to be at the end of a Replicator anymore
  ("FILTER#::ARG" is acceptable now)
- A Replicator can now inject a single number into a key like
  (A#::B# --> A1::B1) if it is not nested
- Merge new debug menu entries from master (better way coming up)
- Heavy maintenance work

This is a squashed commit of 26 commits with the following commit
messages:

Split up some dynamic panels functionality
This is a first step to trying to enhance their logic.

Add test XML for dynamic panels

Try new dynamic panels syntax
At least for developing replicate=true and template=true are dropped in
favor of option nodes like in other panels.
This will make structuring clearer and can be reverted for more
stringency later.

Save possible child panels to container

String operations instead of regex

Multiple # replacements possible

Include Replicators without key to search

Detect if Replicator can replicate Replicators
... and couple this with the start of better (more clear) # --> number
substitutions
(all of these are intermediate commits)

Use info when reps can replicate reps
If not, all occurrences of "#" should be replaced
(moving forward with issue 826)

Propagate replicator child keys to potential template

Try to handle nested Replicators

Back to "replicate=true"
The added verbosity does not seem to bring benefits, and for at least
one thing it's better this way (no cascading into finding the
appropriate key, in a Selector e. g.)

Mini-Cleanup

New lookup logic for Replicators

Support 2 levels of rep/sel nesting

Cleanup
Remove lots of debug code
Add comments

Cleanup, comments

Re-add lost changes

Allow empty Replicator keys
Now if keys are empty use the new, if they are not use the old logic

Handle Replicator help

remove test xml from version control

In debug mode, show how long building XMLs takes

switch to release

Add panel search debug functions
This can be useful to check if unwanted hidden panels are somehow being
created

Add comment

This gets rid of an inconsistency where on macOS CMD+H was
already reserved for hiding the window. It's nicer anyway
and we get rid of an almost empty menu ("window").

Maybe something like this should also be done when saving...

Otherwise, window size settings etc. would be saved as-is on the next
program quit, making clearing these automatic position settings not
very effective (would have to go through command line args).

This feature has been broken with a commit in April... now it should
work again.
I. e.: If unknown keys are read in, they will be shown (and highlighted
as invalid) in the Preview Editor and also saved back out to the file
system.

There are potentially two warnings the user can cancel (file exists
and unsaved changes); for the latter the internal file path would be
set even if the user has cancelled. This has been fixed.

And remove obsolete function

When opening context help the topic can now be anywhere on the page.
Also: QTabWidget::clear() clears the tabs but does not delete
anything... oops. Now we do this manually potentially saving big amounts
of memory and lookups.

Some further restructuring

Add base functionality to the new Help window.
For now, it displays all content in one window.

Getting the tabs right will take a couple of commits... (an additional
abstraction layer is needed so that the tab bar can be exchanged and is
not coupled to the main window)

After hours of fighting, I managed to implement a workaround. The
problem is that when creating an ini file from scratch (for example for
MeteoIO) and running it directly (after saving it to a file), the
workflow output path can not be read (${key:OUTPUT::METEOPATH} can never
be read, it is actually empty). This comes from the fact that
MainWindow.getINI() does not contain the same keys as in the INIParser
just after saving... So the dirty fix is to copy this content to
MainWindow.ini_ just after saving so the WorkFlow object has access to
the user provided configuration. Hopefully, a clean fix can be developed
at some point.

Erase 'close settings' menu. There is now a very visible tab close button and no other program has this. ESC still works.

Thanks to the bold items I see that the preview toolbar was not being disabled together with the menu. Thanks to the Preview editor I see that loading the settings would cause the application name to change.

be given - this will flash the frame's border, enabling contextual help.

Add possibility to show the user guide with a specified tab opened. Use this to link to the Preview section from the preview menu.

Trying not to use the term 'GUI' in the Preview menu... show the application's name instead (at the time of the preview click)

Add 'new tab' preview menu, listen to the print command (to show preview) in the preview itself, the Logger and the About window. Show the logger on STRG+L from the preview and about windows.

The idea was to always be able to start writing an INI, but without an
application highlighting is off anyway and this way everything is
connected better.

read from strings).

Use this opportunity to get rid of semi-confusing initialization
function names that were left from the very early design phase.
Make the MainWindow's openIni() available to the outside.

Much more user friendly INI warning log messages. Also, now if and only if warnings/errors occur when parsing an INI then an 'opening ini_file...' is logged once. Better startup log info. Scroll to end of log when logging a new message.

This is not only necessary for new features but also cleans up a
lot.

This is not only necessary for an upcoming feature but also cleans up a
lot.

Remember splitter sizes also when hiding/showing the Workflow - this makes toggling the Workflow via the menu much more user friendly

Re-enable possibility to move the toolbar around for small screens, but fix it per default (can be un-fixed via context menu).

More work on empty Number panels: starting with a key press now works as expected (more or less). Choose hiding color dependent on whether it's optional. Fix bug where clearing a Number via the context menu would not set the appropriate styling in motion. Feel free to revert to tiny font if more things clash...

The color scheme has been redesigned and now follows Solarized (https://en.wikipedia.org/wiki/Solarized_(color_scheme)). Instead of directly coding colors in the code, they have all received symbolic names and then the names are mapped to a specific color. On the long term, we will be able to offer several color schemes, like Solarized, osX, Windows, etc
