... to prepare having "valid" icon

Also switch warning colors

Now if Qt recognizes a color string even if we don't define it no
warning is shown (less clutter from the dev help).

The virtual stations are given as "VSTATIONx", not "POSITIONx"!
Moreover, more links to the online documentation have been added and the
syntax highlighting (in the PreviewWindow) now supports the coordinates
specifications (otherwise, coordinates provided with ";" were shown as
comments).

A few more icons have been added and a few colors tweaked for the dark
theme (sorry)

Move one more function to 'os' - now only small tweaks are left scattered in the code and the core OS functionality is bundled.

(Because the rest of INIshell is very clean concerning OS-specific code, so it's nice to collect it)

Remove 'SAFE' option for dark mode, because INIshell is not going to run from the same settings on different machines... switch the settings page tab color to solarized.

Mathias, I was not sure if you would like to try darkmode on Windows
unless disabled. The logic for it is in colors.cc::useDarkTheme()

I always expect something to happen on Strg+F in the preview... so the find function has been implemented.

Outource some code instead of tripling it. Closing the preview via key
board is a bit more intuitive (strg+w closes one tab after the other
until it finally closes the main window).

Now the QPalettes are not used, but all colors go through our getQColor() function. It detects if a light or dark theme is used and swapps a few colors accordingly

Now, all keys (including those having a default value) are printed out. This is not ideal but until another solution is implemented, required in order for the generated ini files to be usable. Moreover, default values in spin hboxes are now written with a very small font in order to hide them from view... Again, not ideal but it will do until a better solution is implemented.

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

Disable panels' context menus for grouping elements that could show up on a few pixels. Minor XML tweaks and (very) minor code optimization.

simulation. This is work in progress of course, but there's already a lot of information for
the interested user, and it should be more than enough for people knowing
INIshell v1. A few minor tweaks along the way.

text when the INI is empty

Use new settings wrapper for last visited INI folder and add context menu to open INI files and folders on the file system

More (and more detailed) error messages in the workflow panel, log those errors to the main log also. Don't clear them with a timer, but rather on the next button click

Skip over comments before root node, add 'open in editor' context menu for XMLs, show the application's name in the title, shortcuts for 'row' and 'column', add Spacer panel, smaller layout fixes

whole sections.
