The current set of bluetooth modules only support up to BlueZ 4. Since
the BlueZ API when through a big change with the release of BlueZ 5 the
modules will be forked into a new set for BlueZ 5.
This commit also fixes the spelling of Bluetooth (it's a trademark which
should always be spelled with capital B) and the spelling of my name,
and also update the copyright note dates throughout the Bluetooth
modules.
