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
https://jira.ets.berkeley.edu/jira/browse/CYB-35
@NolanChan can we fix this, just add an breaking line to the end of the file.

Would be good to add `editorConfig` file (see CalCentral)
