Use fallback when dobot hears trigger word in #events

#90 (comment)

When Dobot hears it's trigger work in #events that doesn't include a meetup it should use the fallback and announce the next upcoming.

I don't think checking the #events channel is the right thing to do here. Instead I think checking for "when is the next" can be checked with a fallback. Have we every had any incorrect Dobot responses from that phrase?

But that would break if people ask "When is JSOxford"… 🤔

I figure it'd make sense to require a "when…" or "what…" prefix? At the minute, it's aiming to respond to "is there a jsoxford meetup", but the regex is super lax, and matches "is there a something".

Edit: Not to mention the latter half of the regex is totally pointless and doesn't do anything:

/^(?:when|what)(?:.?s| is) the next (.*)(?:meet up|meetup|event|talk|party|hack|shindig|gathering|meeting|happening)?/i
/^(?:are|is) there (?:any|a) (.*)(?:meet up|meetup|event|talk|party|hack|shindig|gathering|meeting|happening)?/i
/(?:when|what)(?:.?s| is) the next (.*)(?:meet up|meetup|event|talk|party|hack|shindig|gathering|meeting|happening)?/i

All of these list a bunch of synonyms for meetup, then the final ? makes the entire group optional.

Edit the second: Wait, it's not totally pointless. It's to allow for "when's the next jsoxford", as well as "when' the next whatever meetup" – though you could handle that with a well-placed $ perhaps… 🤔
