Title: Allow conditional disabling of row re-ordering 

I needed to be able to conditionally disable re-ordering of certain rows. Since the `UITableViewDataSource` protocol already has the method `tableView:canMoveRowAtIndexPath:` I decided that would be the cleanest way to check if a row can be moved or not. The method is only checked if the dataSource implementation implements it.

At the start of the long press gesture, if the dataSource implements `tableView:canMoveRowAtIndexPath:` and it returns NO then the gesture is cancelled.
