Those shortcuts are system-dependent (and in fact don't even work on my
Ubuntu), so now we try to fetch the native key sequences.
Added a few more why not...

This way for consecutive read-ins it is more clear that stuff is
happening. We do keep error messages though so the user can always click
on them.

Glancing at the key label "add command" I expected I must enter a
command... now I know it's a station ID even without the helptext.

No reason to restrict this to a text-only-Selector: we can access the
internal textbox easily

This should be okay to do now and it finally gets rid of setting object
IDs later (and not deep in Atomic).
It also makes tooltips work normally.
Also added XML error log entry if a Selector is given a key.

small simplification: textmode="true" is replaced by detecting when
no dropdown options are given

This way a Selector's child panels can have nicer help texts.

This was prevented because we don't have a "replicator" XML parameter
and so only the children's namespace is available.
For this, the new tag "rephelp" was introduced because I could not think
of a better way to do it (making a Replicator an independent node also
has its drawbacks).

(and use a separate #define DEBUG_TIMERS for it)

- 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 can be useful to check if unwanted hidden panels are somehow being
created

Cf. updated issue 872 for the problem this brings, but it should at
least be consistent

Now specifying validation="coordinates" validates the string against a
fixed coordinates regex and either prints the warning sign or a globe.

Added new ENABLE_XXX_FILTERING keys, code factorization in 1dinterpolations and new option for decimal dates in CSV plugin

Cf. issue 873

The name was a relict from the very first day of project structuring,
but this name here makes for much much nicer tab-completing to source
file names...

Merge "file selector" changes

Also a logic change: The Number panel does not allow free text
anymore, i. e. if something is entered it _must_ be an expression (at
least for the warning to go away).
An exception are plain numbers, also possible in scientific notation.

I. e.:
2+2 <-- not ok
text <-- not ok
${{2+2}} <-- OK
${env:VAR} <-- OK
123 <-- OK
10e-3 <-- OK
(empty) <-- OK

This should fix issue 872 where mounted shares are not visible on Mac

This worked when the help file was its own "application" in the main
GUI. Would be no problem to generalize, but "for the moment" just note it
like this.

This way, if a "validate=..." property is set in the XML, this has
priority and the warning triangle is shown if coordinates are entered
(which do not fit the user specified regex).

No more "invisible" link, added tooltips

Now we have small icons to make things clearer

... to prepare having "valid" icon

Also switch warning colors

There was some messed up code left from when it was only frames we could
highlight. Much better now.
