add "/shoutout" command

[olafyang]

Description

This pr adds a new "/shoutout" command which calls the helix api and shouts out the specified user.

Add:

• /shoutout <username> calls chat/shoutouts of helix api and gives specified user a twitch shoutout.

It seems like twitch is returning a 500 for all errors excluding 429 rate limit . Trying to shoutout an user who's not a mod gives back to following in the log. Therefore I can not provide more detailed error message for now.

chatterino.twitch: Helix send shoutout, unhandled error data: 500 "{\"error\":\"Internal Server Error\",\"status\":500,\"message\":\"\"}" QJsonObject({"error":"Internal Server Error","message":"","status":500})

I'm only able to replicate this issue when the shoutout sender is not a mod, I receive back a correct 401 when the moderator_id does not match the relevant oauth token, as well as a 400 when from_broadcaster_id is not live/has no viewers.

Typos are fixed in e52f8bb.

I've also added some error handling for the api.

Looks good overall, some nitpicks with error handling & where the code is located

[olafyang]

oops i forgot to return at the anon check and the argument check, i'll fix them in the evening once i get home

[pajlada]

Currently fixing the merge conflicts, will solve the returns in the same batch

Also you'll want to do it on a branch after you clean up your master branch, as creating this PR from your master branch has made a mess for you 😁
