better network logging

[choxi]

Opening the web console currently shows a continuous stream of messages from the network:

This makes it really difficult to debug potential networking errors. For example, right now it seems like there's a bug where one client continuously applies to same delta and gets stuck in a loop but it's hard to assess because there's a stream of messages even when there's no user activity. Could we filter it down to only when a client sends/receives deltas?

Console logs are quiet now, want to close this?
