Pixel perfect for tablet contact editor

- Remove a bunch of files because now the tablet should
look like the phone layout

- Fix padding / margins

- Don't allow phonetic name to be deletable (it would
just clear the field) so that the structured name
and phonetic name now line up (UX decision)

- Make text in editable fields centered by
setting a specific height on the edit text field
if it's not multi-line text
