bump maxConnections to 100

10 seemed too low because more than 10 friends could be linked to a repo
over tor, and if all were running the remotedaemon, which makes a
persistent connection for change notification, then the 11th friend
would not be able to access that repo.

100 might be too low, but it's a much larger group of people. And at
that size group, it probably makes sense to structure the network so
that 100 peers are not all trying to access one central node.
