URGENT: Update to use Meetup v3 by August 15

[SeanKilleen]

Per tech-meetup-website/tech-meetup-website#6 (h/t @caseywatts)

Meetup is deprecating v2 and charging for OAuth consumers after August 15.

This is...disappointing.

I'll document the steps to fix this and try to get the site future-proofed.

The good news is I don't think we pay extra, as long as we are already paying for our meetup org.

Just applied for a n OAuth consumer as well.

@kalimar FYI my OAuth consumer came in. They didn't contact me about it like they said they would but I see it now.

[caseywatts]

fyi tomorrow is the day this will break

[kalimar]

ack.

[caseywatts]

there is a really easy solution Robbie found to get this working again! Can't believe it's this simple :)
