Subject: [PATCH 1/2] Speed up bazaar by simulating bzr root with bash

The PS1 line took forever (~1s) to display in bzr branches, because bzr is slow.

I increased the speed by eliminating the call to bzr, and replacing it with a modified bash script which I found here:

Subject: [PATCH 2/2] Fix broken bar_dir() function, Improve speed.

The previous commit didn't know what to do outside of a bzr repo. This fixes it, and makes it a bit faster.
