reduced cooldown time for ConYard to 5 secs.

8 seconds cooldown time for conyard seems unnecessary and a bit long. Reduced to 5 seconds. The build radius on its own will probably deal with most basewalking problems, so the cooldown time isn't as important. 
Increased Turret and Guard Tower's cloak detection range to 5. They need the range, especially since they are relatively easily destroyed by stealth tanks.
