Add support for webcal:// links
Pitch
See https://en.wikipedia.org/wiki/Webcal
I've been trying to subscribe to an .ics URL and having a very frustrating evening. The attempt to use a webcal link was my last chance but neither Tusky nor Mastodon-Web recognized it as a link. I'm starting to request its support here first...
Motivation
Whoever wants to advertise a public calendar could use the webcal:// scheme to make it clear what the resource is about. The current alternative is to use an http(s) url but then the browser would need to react based on Content-Type ...
In any case, webcal is a IANA recognized scheme so I dont' see why it shoudn't be supported: https://www.iana.org/assignments/uri-schemes/prov/webcal
Tusky doesn't make any links clickable, that is always decided by the server. Changing this is not trivial and I think its nice if all clients have similar rendering behavior, so I'd rather not add this to Tusky.
Ok then I now filed it here: https://github.com/mastodon/mastodon/issues/34598
I'll let you decide if this here needs to be closed
