Got Demo Closer to Mobile Testing

Made a mobile style sheet and added media queries to index for change
logic. Moved both to their own folder. Removed #log from index to make
it easier to test mobile. Changed the Crab object of DrawUpdateObjects
so that the claw starts in a logical position and it's movement is bound
to the crabs maximum reach. Move the Crab object into the constructor of
Director so it is easier to access. Also extracted it from DrawObjects
so it can be independently called.
