Added support for the D programming languge.

It is still a bit rough around some edges, particularly with regard to multi-threading and operator overloading, and there are some documentation bits missing, but it should be fine for basic use.

The test-suite should build and run fine with the current versions of DMD, LDC and Tango (at least) on Linux x86_64 and Mac OS X 10.6.
