Compact contact editor UI tweaks

* Move delete ActionBar icon option back into the overflow
* Move the "More fields" option back to left alignment and
  give it accent color
* Make unfocused fields 25% black
* Layout/padding tweaks
  - Remove the 0 bottom padding on names so that all fields
    have the same spacing between each other
  - Use the min edit height on the "More fields" row
    so that the spacing is the same as the other fields.
