Blobs will slowly regenerate health when pulsed. They have a second cooldown after every pulse to make sure 5 nodes aren't healing them too quickly.

Changed how the overmind hud was updated so that it was more accurate. Instead of updating every life() it will update everytime the blob core health changes and everytime the resource count changes.

Renamed the expand power to "expand/attack", to make it more clear to new blubbers that you use it to attack people.
Typo fix
