Title: Add queue_size arg for all publishers

Otherwise rospy gives warnings on indigo. I mostly picked "10" randomly as the queue size. The one exception is that I used 1 for the queue_size of the cmd_vel publisher, since that's a pretty common thing to do (robots always want the most recent command)
