Christopher Haster 1f13006e36 Added dir navigation without needing parent entries ...

This should be the last step to removing the need for
parent entries.

Parent entries cause all sort of problems with atomic
directory updates, especially related to moving/deleting
directories.

I couldn't figure out a parser for '..' entries without,
O(n^2) runtime, a stack, or modifying the path itself.
Since the goal is constant memory consumption, I went
with the O(n^2) runtime solution, but this may need to
be optimized later.
