process_tracker_python-46 TravisCI Fails on Tagged Build

Modified the travisci config to include job stages, where the MySQL and
Postgresql environments run and then the next stage triggers off with
deploy.  This should prevent deployment from triggering off until after
both environments have finished their testing.

Closes #46
