bug: missing check to power hatch

[Krogsager]

If the robot is asked to explore while the trap is open, the robot will say it has finished exploring before it is started.
A fix could be to insert the following as initialization

if self.isHatchOpen():
            self.tts.say("I can't move when my power hatch is open")

            while self.isHatchOpen():
                sleep(1)

This is right, you can use the ALMemory key BatteryTrapIsOpen for this matter.
