Add JS1kbm

An old-school demo party in the new age. Building a JS1k demo in about 17 hours. I don't think this needs more explaining? :)

Cost: Location, food/drinks, [prizes], jury bribes
Admission fee: Whatever is needed to cover the cost, or none if the costs can be sponsored.
Location: I got nada, I could use some help with this.
People: I have _no_ idea how much interest there might be, and of course it depends on the location.
Date: Date is open for debate, but I think it'd be good to do it before cssconf, but I don't really want to do it too far before jsconf. So my preference would be the 11th.
Time: start early so we can finish before mid-night. Maybe 8am-11pm? We can announce winners right there and then, or maybe at rejectjs, or maybe at jsconf. I'm flexible.
 
I think it'll be super cool and fits perfectly in the jsfest idea. I have no idea how many people will turn up though. Obviously this is partially influenced by the prizes, if any. And partially by how early in the week the event will take place.
