Cerebro performance

[Michael Stone]

RPMS and better developer documentation will probably appear tomorrow,
as soon as Polychronis and I manage to cut a release.

As for the 'sugar/telepathy' help: the plan is to fill in the stub
'telepathy-cerebro' Telepathy ConnectionManager, then to implement a
cerebro_plugin in the Sugar Presence Service. This will get us a working
mesh view. Then comes Tubes. :)
