User Interface Improvements

[adambray]

There are tons of user interface improvements that I'd like to see.

Things that need to be improved:

Deactivate users checkboxes aren't aligned
Clicking User Admin should take you to manage users first
Notes need to go in system-wide consistent note boxes (see stats for example)
Mass Add User

We need to really look at the Shifts index view and clean up the layout of things like 'Sign into blank', 'subs', 'upcoming shifts', etc

Things that need to be exposed:

Kilroy and Stickies Controllers
Uncheduled Shifts for non-admins
