Preserve SideOfPier, Target{RA,DEC}, SlewSettleTime, Move axis across connections
Added support for the GW Command. Removed the implementation of Tracking Set as this does not do anything in the code. Set Can Set Tracking to false. Get tracking always returns true is the GW command is not supported.
Move SideOfPier, TargetRA/DEC properties to SharedResourcesWrapper
Add SlewSettleTime and IsLongFormat to SharedResources interface
Also ensure that digit precision is set during initialisation
Make further properties multi-client and thread-safe
Move MovingPrimary, MovingSecondary, EarliestNonSlewingTime to SharedResources, make all new properties thread-safe (atomic) operations.
