Support more third-party account connections

I don't think the connections is a good idea. Instead the linking that you can do on Mastodon is better as you don't need to connect and be at risk of losing accounts or being stalked upon. Mastodon allows users to add links by adding two empty fields that can be filled in. One for the title exempli gratia stoat.chat and the other for the link username#0000@stoat.chat
