Fixed routing issue

I've fixed the routing issue (grunt serve:dist now works properly).
Ralph and I discuss this in the Google Hangouts but the long story short is that our routes in main.js were wrong because they were absolute references (rather than relative references).

I made a couple other changes, including changing from ui-sref to href. I'm not familiar with ui-sref and was not sure if it was contributing to the issues. If any of these changes conflict with what you are working on (re: Kevin / Peter), please let me know and I can fix it.

I've also laid down some groundwork on Twitter in this update.
