Robot-related improvements based on feedback from Sid:

	* event/sched/event-sched.h, event/sched/event-sched.c,
	event/sched/rpc.h, event/sched/rpc.cc: Send a notification of the
	start of event time and timelines.  Add a '-r' option that forces
	it to use the default rpc path (so dan can use a custom
	scheduler/rmcd/etc on ops).

	* robots/GNUmakefile.in, robots/emc/GNUmakefile.in,
	robots/mtp/GNUmakefile.in, robots/primotion/GNUmakefile.in,
	robots/rmcd/GNUmakefile.in, robots/vmcd/GNUmakefile.in,
	robots/tbsetdest/tbsetdest.cc: Add a control-install target.

	* robots/primotion/garcia-pilot.cc: Take out some experimental
	code.

	* robots/primotion/dashboard.hh, robots/primotion/dashboard.cc,
	robots/primotion/pilotClient.cc, robots/primotion/wheelManager.hh,
	robots/primotion/wheelManager.cc: When doing a COMMAND_STOP, make
	sure we only send one update packet, an idle or an abort.  Also
	send back the actual distance travelled/pivoted.

	* robots/tbsetdest/tbsetdest.cc: Don't output setdest event's w...
