VESPERS: Added the actual size space as a label.  Added the exposure period which is supposed to always be set.  Changed the look of the start and stop buttons for the Pilatus.
Created a new action to replace the AMControlStopAction.  Changed AMMotorGroup, VESPERSAppController, CLSMAXvMotor, and VESPERSPIDLoopControl to use the new actions by getting rid of the old ones.  Everything is buildable.
