bzr serve -v should show live server access logs

[Daniel Clemente]

$ bzr serve -v
listening on port: 4155

Now a client connects to the server. The server displays nothing, and the administrator who ran that command can not see whether they downloaded the branch or not.

I expected:
$ bzr serve -v
listening on port: 4155
