Use precise64 basebox from files.vagrantup.com
Ignore .vagrant file
Update to newest puppet-apt, now with correct attribution

Previously, the README file in modules/apt/ had its copyright
information stripped; I don't know why.
Tweak lua-dbi puppte module, remove unneeded lua-dbi-mysql .deb
Use prosody from the offical Ubuntu repositories, it's current
Set correct URL for Vagrant basebox (enables auto-download)
Completely revamped Puppet scripts

The new scripts deploy from git and use both the HTTP API
and the new webclient. I also reworked the scripts in a
way that might make them useful later as a separate Puppet
module. Other components (pusher etc.) are still missing,
though.
Serve the buddycloud webclient on port 10080
