Updated to rails 3.2
Merge branch 'master' into update-to-rails-3.2

* master:
  updating build status
  migrating development on travis
  caching installed gems on Travis
  using test:prepare instead of migrate
  adding the build status
  creating database on Travis
  as rake works, this script is unuseful
  previous task should be migration
  migrations only should be on engine, not dummy (more info: http://stackoverflow.com/questions/14465754/how-to-manage-migrations-for-a-rails-engine-dummy-app)
  we are using RSpec
  deleting rdoc
Remove deprecation warnings
Updated ruby version
Downgrade ruby to 2.0.0
Update to rails 3.2.18
now we are using Ruby 2.1.2
