Disables Bluetooth cell when Lock Screen cell is set to NO
Disables Bluetooth cell when Lock Screen cell is set to NO

This mimics existing behavior.

It works by intercepting cells in the UITableViewDataSource protocol and
if a cell corresponds to the bluetooth specifier, it correctly sets its
enabled value based on the Lock Screen cell. Similarly, when the Lock
Screen cell is set, the enabled state of the Bluetooth cell is set as
well.
