The 2.0 version splits phobos into druntime and phobos libraries (thanks 
to Sean Kelly). This will enable both Tango and Phobos to share a common 
core library.

There are a lot of structural changes that go along with this, so expect 
some rough patches with this release. It may take a followup release to 
file them down. There's also some renaming of imports and function 
names, as a compromise with Tango names.
