This was no longer installing irods for 3 reasons.

- postgres wasn't ready before irodssetup
- irods 3.3 tgz moved to a different repo
- package language-pack-en was needed
Upgrade to Ubuntu 14.04 LTS and postgresql 9.3
Use Vagrantfile API 2; vagrant-cachier if present
Merge pull request #2 from ajm475du/master
