Use Travis CI and github integration

- Free for public repositories
- Need to set secret key base (copy travis specific file)
- Also copying a database.yml file so that local credentials can be
  different
- Needed to Update uglifier
  * Travis build bundle audit alerted me to this issue:
  * mishoo/UglifyJS#751
- Could leave off the rvm ruby version and let it use the
  `.ruby-version` file, but this is a beta feature (warning printed)
