Feature/action manager qicon import

[Ashwolaa]

Qt6 comes with its own library for icons.

This patch now allow direct import of Qt's icon with the action manager either loaded it directly as icons or through their keyword

Syntax goes as:

self.add_action(short_name='refresh',name='Clear', icon_name='ViewRefresh', tip='Clear filter', checkable=False,)
self.add_action(short_name='delete',name='Delete', icon_name=QtGui.QIcon.fromTheme( QtGui.QIcon.ThemeIcon.WindowClose), tip='Delete filter', checkable=False,)

there is still some cleaning to do and a try/except statement to add. Also could you modify the docstring to explain what are the options for the icon_name:

• png file name in the icon_library
• enum name from the QIcon.ThemeIcon (Qt>=6.7)
• a Path to a png file

Well I did the review, there are things to do on your side ;-)
And you can add the QIcon as potential input. Make sure to create a test to try it please!
