Some major surgery on the sun module. Updates to the client were gated 

by a "mode" check. That mode check has been removed (it didn't result
in any change of behavior anyway). Also added a command line variable
update to set the sun position time offset (offset from the system
clock). Default is no offset to preserve existing behavior.
