Somehow sending friend requests broke.  In the meantime however, lists
for pending friends and accepted friends now work.  So they can now be
connected to their respective activities.  Will create activity to allow
for accepting and rejecting of friend requests, and the friends page
will navigate to the share location page.  Finally the newsfeed will
handle all locations that have been shared with the user using another
list.  Now that these are understood this should be easy.
