Add files for CI support

These changes make it easier for both humans and computers to run the spec tests

* Add `rake spec_full` and friends, which automatically checkout dependency modules
  prior to running spec tests
* Prepend fixtures modulepath instead of overriding
* Add a Travis-CI configuration file to enable easy CI
