Since the move to GTK3 custom color support is extremely hacky and buggy:
- It relies on gtk_widget_override_color() which is deprecated
- Only one call to gtk_widget_override_color() is functional, successive
calls are ignored, leading to the menu not changing colors when the custom
colors are changed or enabled/disabled.
- RegenPlugins leads to a loss of color.
- Theme changes are broken due to overridden colors.
The feature is also very niche and quite unecessary. If a custom color is
better than the default one we should apply the change in the theme or
define a new theme which inherits ours and simply defines the menu
differently.
The way to do this, in line with GTK's design, is via CSS at theme level.
* initial cleanup with some debug messaging
* further cleanup, mostly coding style
* - more cleanup, and speed-up
- more fixes, including many icon and encoding related issues
- replace some icons and remove compile.py
- prepare for python3 port as much as possible
* remove some more unneeded files, few left-over cleanups
* move some external scripts to python3 already
* Fix and clean up add_search_suggestions and add_apt_filter_results logic
* more cleanup, thx Codacity
* fix issue with a path
* add a killall to the test script, fix a method declaration
* fix custom colour setting
* keybinding: re-add GdkX11
* re-add mint-common dep
* Use os.path.expanduser("~") instead of os.environ
* revert re-add GdkX11, but import Gtk first
