Add a "Distribution" object that wraps a sys.path entry with metadata, and

can extract its name/version/pythonversion/platform if built from a .egg
filename.  Later, distributions will be able to add themselves to sys.path
and request that their dependencies be added as well.  Also, added some
real-life version test cases supplied by jemfinch.
