Travis CI to deploy snapshots to nexus

It would be nice if we could get travis ci to run the "deploy" goal so that every check-in causes snapshots to end up in maven central. This would make it more painless for users that want to stay bleeding edge to depend on Fluo without the need to build it themselves.

Start by locating the repository's Travis CI configuration and Maven build entry point, then inspect how the deploy goal is currently handled. Done means each check-in can publish Fluo snapshot artifacts to Maven Central through Travis CI without requiring users to build them locally.
