Remove more editor view classes

Got rid of KindSectionView and the base and read only editor views.
Moved most of the read-only editor field rendering logic to
CompactRawContactsEditorView.
Dropped the expandable functionality of the read only view.
Dropped the edit externally functionality as it doesn't look like
it's being used.

Test:
Viewed the single raw contact only view from the account list.
