Uses 'rake cron' to poll all known repos for data each night.

Runs on Heroku cedar stack with MRI 2.1.2

To run bundle install:

PATH=$PATH:/Library/PostgreSQL/9.3/bin/ bundle

A couple notes after going through and fixing it so migrations work from an empty database again:

• Always save! or equivalent so that exceptions will be raised.
• Do not update stats or counts in the migrations. This breaks when the db structure changes later on - you'll end up trying to work on tables that haven't been created yet.
• Plan on running rake cron to load data immediately after rake db:migrate since you can't do an update_counts from within migrations.
