Add easy pipe handling library. Use it to find real git repository path
This adds a new class, PBEasyPipe, which can do most of the pipe handling in an easy way. We use this to call `git rev-parse --git-dir` to find our current git repository. This means that we can now call GitX within a subdirectory :)
