Fix 7" tablet layout

- Add sw680dp folders to distinguish 10" devices. Move some
files in sw580dp folders over to sw680dp folders.
Otherwise 7" landscape/7" portrait/10" portrait are approximately
similar by splitting the screen 50/50 between the contact list
and contact details. 10" landscape is unique in that it
has a 2-column detail page when the contact has social updates.

Attempt to get rid of the sw580dp-w720dp folder by moving
those values into the other folders. This was aimed to exclude
7" portrait from 10" views and 7" landscape. We don't need the
dimen/integer/style files but we still need it for the action bar
menu options.

- Make quick contact photo square on large tablets so the photo
doesn't get cut off

- Move default phone/email checkmark to the left hand side of
the type text
