Add Portland Has Skill meetup

[kaBeech]

I just founded this meetup and I would like to add it to the community page! 😸

This commit also moves the London Haskell meetup to be in alphabetical order because OCD

Thanks! We need another approval before merge.

This is blocked on #304

This will need to be rebased on master. (You can also drop the change to London Haskell, as we're going to remove it: it's no longer active).

[kaBeech]

Done! Apologies for the extra London edit, I'll remember to open an issue at most next time. Thank you!

[tomjaguarpaw]

It still seems to have a conflict. I'll rebase it myself when I get round to it, unless you get there before me.

[kaBeech]

Oh, that was silly. Better?

[tomjaguarpaw]

Thanks!
