Nydus worm and locust swarm IMPLEMENTED

[warlock]

The locusts sre too slow and their lifetime too short. This makes the nydus worm very ineffective. We should increase the licust speed and lifetime. Cooldown time for spawning should also be reduced.

A spawner unit is always more complex to balance, and it's better to avoid this type of unit getting obnoxious. Eg. Slime is nicely balanced as itself and the minis are really weak per se.
Having said that, Nydus actually seems too weak for its cost, I agree. The locusts could be a bit faster. However, the vanish time seems fine, and they can be spawned every 2 turns which is already good enough.
I'd also buff the Nyduses damage so it can defend itself properly and also be used for tactical burrow/surface operations.
