Make it able to read another Barcode
Refactoring and code cleaing
Better light value
Better wall_hit behaviour (faster and more accurate rotation)
Hopefully better recognition if the robot is scratching at the wall. This implies that there will be no left wall (in the maze) more far away than 254 ;)
Bugfix: If a light line was detected, go to the action() method - no matter what!
