Travis-CI integration, stable for Linux+Railo+MySQL+PostgreSQL+H2 DB

To integrate CFWheels into Travis-CI.org continuous integration service:
1) Visit https://travis-ci.org/
2) Sign-in with github account (link on top right). You need to be admin of cfwheels repo.
3) On your account, enable cfwheels/cfwheels repo (from OFF to ON)
4) I recommend to enable "Build only if .travis.yml is present" in the settings
    This is because, not all branches have .travis.yml
5) Create or accept my pull request with .travis.yml inside
....
6) Sit and relax, because all PR will be checked against unit test on all supported environments.

Note: You can also pull this on another branch (e.g.: NOT new-master) to play around first.
