Adjusting provisioner since the reinstall

Switching to Honcho based processes as opposed to things started through
fab
Adding Honcho/Foreman capabilities

Fixing up Berksfile dependencies, adding Procfile for use with
Honcho/Foreman. Adjusted bootstrap.sh script to correctly pass
environment variables being instantiated by Honcho.

For future reference, all processes that require environment variables
should be run through Honcho/Foreman (so we don't need to keep all the
environment variables in the shell)
