Hordes nolight

Hordes.
 - more zombie groups, but less monsters count in it.
 - crossovermap signals and hordes moving
 - information about horde size and speed on map
 - more fast debug
 - tracks
 - removed light signals 
I remember that filling funnels don't work correctly. Weather_log - is global? Finally i don't think, that this way is more better than run over vector<int*> periodically. With large count of NPC and wild animal groups iteration count  be will be very different.
