blackbox: adds a blackbox extension

Adds a blackbox extension that listens to ui.log() and writes the messages to
.hg/blackbox.log. Future commits will use ui.log() to log commands, unhandled
exceptions, incoming changes, and hooks.  The extension defaults to logging
everything, but can be configured via blackbox.track to only log certain events.
Log lines are of the format:  "date time user> message"

Example log line:
2013/02/09 08:35:19 durham> 1 incoming changes - new heads: d84ced58aaa

            self.debug('%s:%s %s/%s%s (%4.2f%%)\n'
                     % (topic, item, pos, total, unit, pct))
        else:
            self.debug('%s:%s %s%s\n' % (topic, item, pos, unit))

    def log(self, service, message):
        '''hook for logging facility extensions

        service should be a readily-identifiable subsystem, which will
        allow filtering.
        message should be a newline-terminated string to log.
