moving wxd to github

[Andrej Mitrovic]

Well the cool thing is I can use wxGlide to generate C++ code, and
convert that to D. I tried it just now and it seems to work, but
converting everything by hand is a bit of a chore.

The biggest problem by far are the enums, since wxWidgets enums don't
have a "tag" while the wxd enums do. This might be fixable via some
quick shell scripts.

However even though D is C++ inspired, I just have a much easier time
converting python code instead. I think this is because wxGlide puts
everything into header+implementation files, and this is a chore to
convert to D, whereas the equivalent python code is in one file and
much shorter.

I definitely think I'll start using wxd from now on. :)
