Remove the ability for blobs to spawn offstation

[Roomba]

A blob wins by spreading out over a certain amount of tiles. Every tile that it sprouts is, by definition, a blow against the crew. It's perfectly reasonable to start on the station and half-ass a blob round. A blob starting in the syndie shuttle and growing over space isn't a blob going 'I want to be a chill blob who doesn't hurt anyone', it's a blob going 'I don't want to contribute anything to the round but I also want to win in the cheapest way possible'. I've never actually seen a spaceblob defend itself with the 'imachillblob' routine in the round itself, it's only ever used as later justification when people point out how shitty it is.
