Initial commit
Added puppet facter
Set virtualbox name
Added optional PHP dependencies
Fixed nginx locations.

The nginx configuration for Phabricator (specified at http://www.phabricator.com/docs/phabricator/article/Configuration_Guide.html) is inconsistent with the Apache configuration. The Apache configuration is correct.

Disabled `always_apt_update` for `apt`
Write host to `/etc/hosts`
Improved nginx rewrites and configuration
Don't exec `storage-upgrade` unless required
Log exec output
Use the `vagrant-librarian-puppet` plugin
Disabled `apc.stat`
Use development environment
Ensure that git modules are up-to-date
Notify `build_xhpast` when `/usr/src/libphutil` changes
Subscribe `storage-upgrade` to the `phabricator` repo
Allow configurable development/production mode
Moved `phd-start` to `phabricator::db` and fixed dependencies
