Fix navigation and focus issues in RawContactEditorView

Remove clickable and focusable attributes for certain LinearLayouts.
These don't seem to be needed in touchmode (since their child
EditTexts/Spinners are clickable anyway), but were messing up
navigation using a keyboard.
This fix only fixes issues with navigating between data kinds in
a single raw contact editor, further fixes will have to be made to
make the entire contact editor usable.
