Explicitly set Rails version

On first setup it was trying to install the wrong version of Rails.
Explicitly set this to 3.2.13 for now until we update to Rails 4.0
Removing vestiges of old non-open-source code
Get away from the sqlite and use Postgres!
Remove users password_id column from db
Remove old omniauth controller until further notice
ApplicationController was missing!

Just adding back this important little piece to the raise puzzle :wink:
Use a environment specific secret token for now
Make specs green with pending

Springloops support is gone, so to get a green test suite just mark
anything that uses old Springloops stuff as pending for now.
