Filling in voidlife

I've updated phykons and shoalers in the wiki.

I really need to come up with a better introduction, wiki-wise, but I guess that means I need to decide on what the elevator pitch is for the gameworld. For me it started out as "compact space" but I am afraid voidspace has gotten too interesting. That sounds funny, but: in Traveller the week of jump is a "bottle episode" situation. I'm not sure I want to distract from that too much.
