ADDED: new activity for editing numbers

Added a new activity to edit a contact's number, as well as all of the relavent information about that number.
FIXED: edit number to update the database

Edit number now writes to the database upon save. AddContact has a bug (since it isnt update after EditNumber) this will be fixed soon.
FIXED: the AddContact/EditNumber update bug

The transition between the two works now.
FIXED: new numbers for EditNumber

AddContact now uses EditNumber to add new numbers to the contact. Also, fixed a bug that Shared Info and book paths would not get update to the database. Finally, found a bug in ManageContactsActivity where click on one of the contact's children (numbers when expanded) will use the call back onItemLongClickListener given a 'bad' position therefore mis-using the AddContact activity.
FIXED: a bug with updating shared info and books

Updating shared info and book paths now works correctly so that if only 1 of the two is deleted then it will still default back to the default value. If both are deleted then both are defaulted back to the default value. Also, found and fixed a bug that the first number of a contact would be treated as a new number in editNumber.
