New Schedules Watch Window added to the TinQTConsole

*  CL:  248
*  Minor fix to the history buffer in the TinQTConsole
*  First pass implementation of the SchedulesWin
*  Support to let TinScript know if the time scale has been altered
(communicated expected schedule behavior to the debugger)
*  Re-entrant "OnDestroy" guards added, since we have no control over
code callinging ::Unregister().
*  Refresh button added to the Object Inspector
