Fix some robot related stuff that I broke with the last checkin and add in
some other tweaks.
Broadcast any goto/stop commands to clients observing the robot.
* robots/rmcd/rmcd.c: Change the behavior to reorient the robot as
the last step in a goto, so we avoid doing unnecessary pivots.
Need to send an init packet to the robot so it knows who is
talking to it.
* robots/vmcd/vmc-client.c: Oops, supposed to use M_PI_2, not
M_PI, when translating from camera coords to world.
* www/telemetry.php3: Make the size of the applet a little bigger.
www/garcia-telemetry/main.xml: Display a log of goto/stop commands
sent to the robot.
