Travis Test Results

Process test results from Travis Worker (particularly travis-guest-api) and store it in DB.

Implementation is based (copy & paste) from travis-logs (therefore travis-logs license is attached as well).

Setup

 # if needed:
 dropdb travis_test_results_${ENV} --user ... --host .. --port ...
 createdb travis_test_results_${ENV} --user ... --host ...

 rake db:migrate
