This PR adds the "alt" theme that is (currently) the only theme distributed with Geany. If https://github.com/geany/geany/pull/4044 gets merged to Geany, it makes more sense to have the main "home" of the "alt" theme in geany-plugins so when some global changes are made to all themes, the "alt" theme doesn't have to be updated separately.
Now the question is what license should the "alt" theme have? There's no explicit license right now. Should it be GPL 2 or later like Geany or something more permissive like MIT?
