WIP. system upgrade

Notable Upgrades

- Ubuntu to 14.04 LTS
- PHP to 5.5
- Apache to 2.4
- Puppet to 3.6.x

Small changes:
- host from iliosdev to ilios.dev
- prettier bash

Work in progress. Do not merge yet.
TBH, I only added it because it does things like show the git branch for the current dir on the prompt, and adds nice things like date, etc.

You still have to enable it when you ssh into vagrant (since you can't source with puppet).

But even after enabling, it just adds aliases and functions (to enable remote debuging for example), so it doesn't really wildly modify the behavior of bash at all.

But, i'm not opposed to just taking it out altogether either so, you guys let me know!
