Various changes and debuging on multiple methods

• Changed the ram method which will now only initialise if the enemy robot has 20 points or less life than Cappuccino or it will disengage in a parallel line with increased velocity in the hope to avoid tracking • Changed the buffer size of the avoid wall method from a percentage to 140 pixels to avoid disproportionate buffers on smaller or larger maps. • Integrated the avoid wall to Centre method in to the onHitWall method in corners to insure robot doesn’t randomly hit another wall.
