🙋‍♂️ Inline post polls

Posts now support inline polls. These are intended as casual, lightweight polls - don't run an election with them.

* Only one poll is allowed in a post and people can change their answers.
* The author and GM (in a game forum) can always see the results without voting.
* You can see the option(s) you've voted for because you'll show up as a red GP icon.
* The question is in the quoted attribute, the answers are on newlines within the tag.
* If you change the poll after voting then the answers will match the positions of the original answers - so add new options to the end.
* You can also run polls where people can vote for multiple answers (multi) and/or see the results before voting (show). See below.

[poll="Was this explanation helpful?"]
Yes
No
[/poll]

To show the results to users before they vote, add the show option to the poll.

[poll="LotR or Star Wars" show]
LotR
Star Wars
Neither
[/poll]

To allow multiple options to be chosen, add the multi option to the poll.

[poll="Which adventures would you be interested in playing?" multi]
Waterdeep: Dragon Heist
Icewind Dale: Rime of the Frostmaiden
Dragon of Icespire Peak
Ghosts of Saltmarsh
Baldur's Gate: Descent into Avernus
[/poll]

You can use both the multi and show options (the order doesn't matter).

[poll="For which systems would you like to see Gamers' Plane tutorials?" multi show]
Dungeons and Dragons (5e)
Pathfinder (2e)
Shadowrun (5e)
Tales from the Loop
[/poll]

If you don't want an anonymous poll then you can add the public option. This will show avatars instead of the GP logo for votes. This option can be combined with other options (like multi and show).

[poll="Are you usually the GM or a player?" public show]
GM
Player
About the same
[/poll]
