zerg: added missing upgrades, reorder few others

[duran55]

I put air upgrades (except level 1) as late as possible. I added everything missing - feel free to remove what you think is not neeeded (overlord vision, etc). Reordered tech/upgrades which I considered more important: Plague for Consume, Hydra speed for Lurker Aspect.

The updated script is tested. I played few games against Zerg, no issues so far.

Upgrade names here just for reference:

overlord:
	upgrade(1, Pneumatized Carapace, 80)
	upgrade(1, Ventral Sacs, 80)
	upgrade(1, Antennae, 80)
	
hydralisk:
	upgrade(1, Muscular Augments, 80)
	upgrade(1, Grooved Spines, 80)
	
burrow:
	tech(Burrowing, 80)

Thanks for this! I've ended up reworking the tech order for Zerg while playing around with this. It should integrate most of the upgrades now, but it does leave out Burrow and Overlord sight range intentionally. I also dropped Consume, as it is probably a net negative given how poorly Defilers are used.
