Integrated paintboard and metal detector control classes more fully.
Added Metal Detector to the sensor class. Now behaviors can access it. Also made it directly return the bool from messages.
Added RungeKutta to the helper classes and changed the odometry to use that instead. Also created PaintboardControl files, changed the Makefile to compile all control classes and deleted Cliffsensor control becase it did not work.
Added Sensors class that abstracts away sensors from behaviors. Stops creatingduplicated sensors for each scout.
