Prevent AGIMUS From Responding To Stuff Like "nice bottle"

It's been funny, but this often just causes confusion and derails a conversation so I think it's time to add terminators for the bot autoresponse to condemnation/praise.

Would be nice if we also accepted it with spaces on either side, so that sentences like "He's a bad bot, but we still like him" will fire even without a period of EOL
