Added logic for global nav toggle.
Global APp Nav:
* Working prototype with broadcast
* Code is messy
Adding an vlnAppNavCtrl.
Remove debug logs.
Fix ngAnimate
* Upgraded angular to ~1.3.0 and other ng packages
* Confirmed that ngAnimate is working as expected
* NOTE: I had an issue with npm update and solved it by running npm update -g in top level of project
Keep Tsankos navigation style deltas.
