Add Travis CI support for testing

Possible?

I would assume it is possible to set up. Would require having an Umple distribution installed, so can compile the converter, then just run the file test/src/cruise/umple/fromjet/MainTest.java as a JUnit4 class.

You could snag some of the dependency code from the main repository. :) That being said, is it worth it? Questionably.
