Attach something other than a file to a card

[ryanprior]

I love that we can attach files (eg images, documents) to a card and I see in other issues (like #564) that we will eventually be able to attach files already stored in NextCloud.

I'd also like to attach other NextCloud objects to my cards. For example:

• Social media posts (eg commentary about this card)
• Calendar events (eg an event related to this card)
• Another card (eg an earlier task for which this card is a follow-up)

It is generally possible to link to these things in the commentary, but like links to files, they don't provide much value or visibility.

This is what Nextcloud projects integration was ment for, however we only support linking to boards at the moment. Linking cards is proposed in #965 so I'll close this in favor of that one.

I tried to link a card to a calendar event today & found I couldn't. @juliushaertl can we reopen this issue since #965 didn't resolve it?

The support is there in the deck app, it is basically calendar that is missing nextcloud/calendar#1504
