CLC-1240 Implement Status Badge Count Indicator for bApps
https://jira.media.berkeley.edu/jira/browse/CLC-1240

First pass.

- Set up a new controller on the launcher bar
- Use a new dummy badges.json to separate functionality from user profile (performance)
- It wasn't possible to have the data-bubble attribute disappear when count=0, so instead used ng-class combined with the always present data-bubble count.
- Some spacing work still needed when bubbles disappear, and need to test with 4 chars (e.g. 1.2k)
