Title: Upgrade to latest modules and git to 1.9.1-boxen1

This updates some stuff to the latest modules. It enables more recent builds
of ruby and more notably upgrades git from 1.8.4 to 1.9.1

I noticed a snag with the git upgrade, that if you have an outdated homebrew
version (as I did), because of a change in the git brew, you need to update
homebrew first with `brew update` otherwise you will get an error like:

```
