modified the pacman and spynnaker front end so that graph mapper is no longer needed for the pacman tool chain section after partitioning and that the utility calls are no longer in existance.

ive also added the call to stop which now uses routing tbales to remove them from the board. (note that due to a nasty of how the spynnaker functions have been split theres a nasty code bit there. where it expects the rotuing tbales which itll receive due to horizontal inhittance. (needs looking at)
