Updating a checkpoint which patches everything in the library.  Also has a non-working version of xrange.  I haven't ported this from 2.6 to the int/long unification.  This is just in case my laptop crashes.  Hopefully I'll finish this up tomorrow and check in.

Most of the tests pass.  There are only a few issues AFAIK, like test_xrange (big surprise) and test_repr.  Basically the longs aren't done.  I'm not sure about floats.  Floats should be rejected in 3k.
File Added: xrange.diff
