Libs: Upgrade Angular to 1.2.0-rc.3
Auth: fix scope issues caused be 1.2.0rc2 -> rc3.
Sprint: Add button to refresh data.

Fixes #19
Auth: Broadcast events.

Fixes #18
Sprint: Remove auto-refresh.

it without some sort of caching on the server, which is hard. Lets just
not do it.
Merge pull request #21 from mythmon/refresh

Add a refresh button, auto refresh, and refresh on login.
