CI: run daca2 on oldest folder
Library: add new "define" tag

This tag will allow to add some preprocessor defs into library.
It would be useful to provide more information about libraries
implementation details. As example GLib's library include tag
was added that helps to detect more memory leaks.

Move astyle options to astyle.ini.

This way we can use it in runastyle and runastyle.bat.

Settings changes:
* specify the files to exclude instead of specifying the files to style
* remove `--lineend` option
* keep the file's modified timestamp
* only show the styled files on the command output

Also change the astyle version check to only check for older not the exact version.

It includes a check if astyle is present and for astyle's version.
Also, it allows drag and dropping files onto it to style them.
