[phobos] automated builds and tests

It's super crude.. it looks horrible.. but it's a start.

What it does:
   forever:
     checkout a fresh copy of dmd, druntime, phobos
     build dmd
     build druntime
     build phobos
     test druntime
     test phobos
     test dmd (quick mode)
     sleep 3600

Anyone want to help make it not look like crap?

Later,
Brad
