Android 5.0.1 release 1
profiles: Make the actions wizard buttons show up

The "back" and "finish" buttons weren't being shown at all in this
layout, which made it impossible to add profiles.

profiles: Make the floating action button more material-y

This makes the FAB look consistent with other fabs across the system,
it adds animated elevation, changes the icon color to white but mainly
fixes the size which was completly wrong.
