Added automated build process for local development work, using virtualenv and ruby-env for sandboxed Python & Ruby environments, vagrant for an isolated PostgreSQL VM, and foreman for heroku-like deployment.

Also moved applications into 'apps' subdirectory, added unit test runner, and performed minor cleanup.
Merge pull request #1 from maaku/vagrant-build

Added automated build process for local development work
Remove comments from Procfile, so heroku can parse it, and fixed faucet URL configuration.
Moved PostgreSQL to a random port, so as to not conflict with other running databases or mapped VMs.
