TravisCI based tests for FW/1

While there's still things I want to do I thought I would open up the PR as I believe this feature is now in a state where it can be used with FW/1 - it meets the "minimum viable product" - runs the FW/1 test suite (although only on Railo) automatically on Github commits so at a high level we can make sure PRs don't break FW/1.  Although I guess maybe hold off on merging into develop until 2.2 goes into master.

Further "nice to have" changes can always be made in future PRs.

Sean - you would need to follow the Travis CI docs for activating the Travis CI service hook into Github for this code to have effect - mainly Step 1 and Step 2 from the Getting Started guide:

.. this PR covers the other steps (configuration and test code itself).
