Zerg: Overlord scouting

[alkurbatov]

Currently CommandCenter uses only workers for scouting tasks. However zergs gameplay is reacher:
a. An overlord could be used to scout the enemies position before (instead?) a worker.
b. When current map contains > 2 players starting points the bot should send an overlord to one direction ( e.g, clockwise) and a worker to another in order to find the enemy faster.

Probably the overlord scouting should be optional and enabled via special flag (as it is a bit risky esoecially against terran) or even used instead of worker scouting (not sure).
