Made sure that CommandString, CommandBool and CommandBlind work as expected, complete with Raw and non raw support. (Implementation is the same as one of the LX200 drivers.)
Reinstated the Real Alt Az methods for the LX200GPS. Changes how the parked behaviour is implemented, so that it doesn’t need to make as many calls.
Fixed the defect when one instance of the driver gets parked, the info is shared to the other instances.
Made sure that the telescope doesn’t think it’s parked for the first Telescope to connect.
