Respond to direct mentions

[hiinaspace]

feels more natural to me than !chaz. The client will autocomplete the mention, and you can do "@chaz respond please" without stepping on the whole command system ('!chaz respond' would be parsed as a command instead).

This depends on a headjack change to pass the full event back (to get at the mentions):
