Remove extra spaces
Add postgres configuration
Probably want en_US as the default for text
We always need a www directory for sharing
Wrap the puppetlabs/postgresql commands for installation in the `postgresql` class
Update readme to remove the Galileo-specific instructions
Update Vagrantfile so that it works with newer Vagrant Versions

Tested with Vagrant 1.3.5

so there is no reason to put the share in a sub-directory.
Re-activate MySQL, because why not?
Run apt updates before trying to install MySQL
