Add support for D package

[evangreen]

Vegax 87 requested support for the D programming be added to the repositories in third-party. He writes:

Hi, I discovered Minoca today and I wanna ask you: what do you think about adding D language on Minoca? IMHO D language with Gdc or Ldc2 compiler has achieved excellent results and also is one of the most scalable languages out there and it has a very low memory usage which is perfect for Minoca, I think it deserves a chance to be included on Minoca 3rd-party repos, unfortunately I don't have enough knowledge to port it on Minoca...

P.S: You can see some reliable benchmarks here: https://github.com/kostya/benchmarks

@vegax87 ... I get GDC built but not it's libs.

Read this as cheatsheet, don't run it as script... some paths need to be changed for your system. CHEATSHEET-4.9:

Houston, we have some results:

Someone knowing more about GDC should take over now removing --disable-libphobos and looking at the resulting errors.
