Remove all traces of previous provisioning steps.

We're switching to Docker for production provisioning! All production
provisioning scripts are moved to fanboi2-docker repo. Vagrantfile in
this repo will be used for development environment provisioning only.
Initial development Vagrantfile.

This Vagrantfile provides a standard development box with the following
packages installed and ready to use:

* PostgreSQL 9.2
* Redis (latest version from PPY)
* Memcached (latest version from Ubuntu repository)
* PyPy3 2.3.1 (Python 3.2.5 compatible)
Setup application in provisioning and PyPy3 support.

The provisioning script now creates the database, setup the application
in development mode including installing its requirement as well as
removing some package not compatible with PyPy3 and replace it with
equivalent that actually works.
Travis.
Install Brunch and build assets on provisioning.
Add sample production configuration.
Rewrite most of the README.
