(svn r2021) Fix: Enlarge _cur_town_ctr from byte to uint32 so that all the towns are considered when growing them even for big maps, where much more than 256 towns are around; reported by Tomasz Dubiński <uboottd@hydra.polsl.gliwice.pl>. The savegame still saves just the lowest 8 bits but that doesn't hurt so much.
