New code swarm

[Jordi Gutiérrez Hermoso]

I made a new code swarm:

Explanation: coloured dots are files and they swarm towards the person
who touches them. When two people touch the same files, they start
swarming towards each other. The little line graph at the bottom shows
project activity by number and type of files touched (it's just a
simple regexp based on the directory in which the files are touched).
People fade away as they stop coding and new people come from the
edges as they start contributing.

I did this code swarm purely from the hg history, with some manual
fixes of the names of people (changeset 424ba638d8f1 for example was
committed by a very interesting user). The old one that I did
similarly by parsing changelogs instead of hg logs, which was a lot
more work, is still available here:

The new one starts at the approximate time where the old one left off.
They're in ogg, so non-ancient Firefox and Chrome should be able to
play them natively. If not, VLC can play it.

Enjoy,
