Improved ranges-calculation speed by adding TONS OF THREADS
It now only takes about 1 sec to calculate an viewrange of 20, instead
of 20mins before the overwork and 31 secs after it
Removed unnused implementions from Controller and Model
Chagned name of BuildingModel's, Builder's and Producing's
getBuildRange() function to getBuildrange() so it fits better into the
game's conventions
Removed unneccessary Sysouts
