Remove limitation that requires @ mention for a bot to receive a channel message

[RichardBronosky]

I am aware of #28 (comment) but it is really a deal breaker for using Teams. I've been asked to move our department from Slack to Teams, but I cannot transition to a service that doesn't "work". I can't imagine why a bot would be limited in this way. It's almost like an "output only" thing that you've made ...but with the ability to sometimes interact with it. It's really confusing as to how this is a good idea for anyone.

It doesn't look like this possible using the bot framework as it was originally designed. That said, I was just notified that there's new functionality "in public preview" which allows bots to be given permission to receive all messages within a team. Maybe this is a step towards removing the mention requirement?
