Thinking of removing Gtk enums and D aliases

[elementgreen]

While working on getting adrdox working with giD, I realized it isn't handling the current way that gidgen generates enums. Currently gidgen creates enums in the c.types module with the original name, such as GtkOrientation. The enum members are TitleCase, such as GtkOrientation.Horizontal, which is different than the underlying GIR API. There is then an alias created in the types module which removes the prefix, such as alias Orientation = GtkOrientation. I'm thinking of making it to where the enums are just defined directly in the types module with the D enum name, since I can't see a reason to have this extra layer. Just wanted to see if there were any objections to this.

O, never mind. C types such as callback functions reference enums/flags. Now I see why they are aliased.
