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.
I submitted a PR, but haven't seen it merged. Noticed that even though I have require=> File[$logs], vhost still tries to create that resource, even though in the manifest it's coded to not do so if it's already been defined... weird bug.
