Further changes by now:

* subdirs() is now dirs().
* fixed compare behaviour for unicode base (unicode has no rich compare)
* __iter__() iterates over the parts().
* the following methods raise NotImplemented:
  capitalize, expandtabs, join, splitlines, title, zfill

Open issues:

What about the is* string methods?

What about __contains__ and __getitem__?

What about path * 4?
