Proposed home screen changes

- Added proposed changes for home screen, including guidance elements
that encourage the user into adding photo, phone or health data bits.
- Updated home template to use UserController, since the profile
elements are also shown on the new home screen.
- Added new filter findHealthDataBits
- Added new directive and partial for sprtid-databit-phone
- Updated styles to support new home screen
- Injected ionicViewService so we can reset the back-button state when
the user  logs out or is logged in from the welcome screen
