Crash fixed: UITextView data detectors have a problem in iOS7 while dequeueing cells.
I solved it by applying a unique cell id according to it's message object address.
( https://github.com/jessesquires/MessagesTableViewController/issues/154 )
Timestamp (date) was reformatted to "MMM d"
Decreased maximum width of message bubbles so bubble does not overlap with Edit mode checkboxes.
