Start down path of new build system:

- Move tests to karma test runner and mocha framework, also adding chai assertions
- Add gulp tasks for testing, watching, concatting and compressing
- Update travis file to use new build system
- Remove jstestDriver stuff
- Reorganize a bit so that it's easier to see what's going on
- Create a dist folder to hold the output of builds (should probably look at having a bower branch/repository where these are held, instead of master)

I'm pretty sure we don't want to push this to master, but that's where this was diffed against.
Create the files necessary for bower and move them into a dist folder.
