Theming

[wherron01]

gnonograms is easily my favorite nonograms application I’ve ever used; I think it generates more fun puzzles than any I’ve used on desktop, web, or mobile. However, imo the blue and yellow is somewhat ugly. Obviously this is subjective, so I suggest letting the user choose at least a color scheme (or respect GTK theme color choices) and maybe fonts or other aspects of the UI as well. Not meshing well with my desktop theme is the only thing holding me back from playing this more often.

@wherron01 Thanks for the suggestion and your kind remarks. I am working on a new Gtk4 version and I will try to incorporate user color schemes in that.
