Documentation for any* dub package, any version

[Adam D. Ruppe]

Gtk-d and DWT are both too big to automatically build on the 
server, but I did some manual work on them.

DWT:

http://dwt.dpldocs.info/org.eclipse.swt.widgets.html

GTK-D:
http://dpldocs.info/experimental-docs/gtk.Application.Application.html


The gtk one has me translating some syntax from C to D 
automatically. I figure I'll do that kind of thing for dwt too 
eventually, so its javadoc renders a bit better too.


These two libs are bigger jobs so they won't be full featured for 
a while, but even these partial documentations are better than 
I've seen available for them before.
