code review cleanup

- in project detail, can use href instead of span and get rid of controller
- for main control, use router provider to resolve project list
- for loginStatusChanged event, pass along data as part of event
- specify radix for parseInt()
- for main view, use href instead of span for going to project detail
- in main controller, simplify filter function
- in all services, get rid of console logging (already done in chrome) and alerts (should be done in app)
- in auth service, return promise for logout
