blackbox: log incoming changes via ui.log()

Logs incoming changes to a repo to ui.log(). Includes the number of changes
and the hashes of the heads after the new changes.

Example log line:
2013/02/09 08:35:19 durham> 1 incoming changes - new heads: cb9a9f314b8b

Currently the blackbox logs the unix user that is performing the push/pull.
It would be nice to log the http authorized user as well so it works with
hgweb, but that's outside the scope of this commit.
