Update reference app design

[fredhersch]

Implement updated UI for the reference app design

Notes
This will be an iterative process starting with:

1. The basic colors, fonts - e.g see Mock splash and login screen #655
2. Form control elements and expected behaviors and handling of error messages
3. User experience and specific flows
