Blob Spore Death Clouds

Made blob spores (those factory units) a bit more useful! On death they will release a spore cloud which will slightly damage (0.5 per tick) people and cloud your vision until the effect wears off.

This will do two things:

 * Encourage people to run away from the blob spores and take it out from a range.
 * Buy time for the blob as people wait for the cloud to go away, or move around it like an obstacle.

Before you mention how smoke spreads all over the place, it will only create one cloud which won't move; effectively discouraging a player from moving on that single tile. Like so..

The damage is so small that you only receive 20 damage if you stand in a single cloud for it's entire life span.
