We agreed that "it's a feature not a bug", the issue is closed, and I'm
still certain that this is necessary and ok. Hence, I'm humbly replacing
the "HACK" flag with normal documentation.

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.

When doing a merge, keep, exclude, etc that rely on a station ID, since
the user might have little control over the station ID we need to be
able to support some flexible naming (including containing '-').

better "unsaved changes" warning.

It should finally be relatively clear to the user what happens when an
INI is opened, and closed seemingly without changing anything - namely
that the application may have inserted mandatory keys.

-Move setting to 'preview' XML section because it exists from another setting now
-Remove obsolete documentation
-Clear status on TerminalView clear ("Process terminated" etc.)
-Remove useless _ from regex (it is checked by \w)
-Extend INIParser unit test with *::EXCLUDE example key
-Cosmetics
(Might want to clear settings with ./inishell -ce)

This fixes issue 829 with MeteoIO's "*::EXCLUDE" kind of keys. Moreover,
the new option for MeteoIO's deGrass filter has been included in the xml
file.

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.

Cleanup so that always writing out all INI values (optional ones too) is the default behavior. This promotes the hack here to a feature request.

Get rid of outdated doc concerning this. Also: Work with the full INI (file system + GUI) for the character transformations.

through the preview (whitespaces, sorting, capitalization)

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.

More end user friendly 'unknown INI key' log message, don't warn of misformated INI files if it's only a harmless whitespace.

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.

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

Add short info text about why the INIParser's == check asserts false, fix special case where an integer would be transformed to a float with decimals (thus failing the equality check)

Log INI errors in command line mode to console instead of opening a message box, and some readability.

Correct wrong personal path for iniqueryparser, and add a check for that... as well as for missing read permissions. Dump minimal settings file with appropriate command line option. Fix bug where a settings XML would not be available yet. Minor cleanup.

Two small fixes for wrong 'unsaved changes' warning: compare case insensitive, and circumvent the Number panel's precision parsing if a numeric INI key is only read and never changed. Also make it more clear that INIshell is working when parsing INI files.

Fix reading order of INI keys (for the moment, FILTER1 = MIN has to be read before ARG1::MIN = ... in order to create the necessary panels. Allow dots in meteo parameters

Add INI key search and some syntax options to Workflow. Add command to change a FolderView's directory (to drag output files out of). Add workflow panel status
