Angular Front-End integration and CYB-35

This is a HUGE push, it includes the Angular Front End addition (courtesy of @ChristianV) as well as basic LTI tool integration (inspired from CalCentral)
Also includes some travis and JSCS files for testing

@NolanChan We can probably remove these, since we don't have these files?
