git mv calcentral_events/* to top level directory

It is necessary to have the rails application at the top level so that

fix dependencies for deployment to production env

- only require factory_girl in development and test environments
- only install sqlite3 in development and test environments. Heroku does
  not support sqlite3 install with ruby-1.9.3
- add pg (postgres) gem for production environment
- add Gemfile.lock
- use faker and factory girl in production just for creating dummy data

Remove accidentally added files:
- Gemfile.lock.orig
