Testing to get travis configured properly

* Add in test.php - this is the main file that runs the unit tests
* Add a configuration.inc.php to the travis folder for running the tests
* .travis.yml is what travis-ci looks for to kick off a build
* add a copy of prepend to the travis folder and modify the configuration
constant to point to the travis folder

* create a copy of qcubed.inc.php
* Clean up some changes that didn't need to be made.
* place a codegen file into the travis folder for custom codegen
* final tweaks to get tests working.
