Add parent submission field for reply threads #386

This adds a new "parent submission" field to the default submission section, letting the user pick a submission's parent from a drop-down. After posting a submission, website services get a chance to react to this and manipulate the child's part however they feel is useful.

Currently, this is implemented for Bluesky, Mastodon and Pleroma, which will set the "reply to post URL" field to the source URL of the parent post, removing the necessity to manually copy those over.

Other uses could be implemented if someone feels like it, different websites have various flavors of post relationships that could be handled this way.

The only time the application acts on parent-child relationships is right after a submission has been posted. That means invalid parents that reference removed submissions cause no harm, they're presented to the user as being unassigned. That means we don't need to bother maintaining the validity of these fields when removing submissions. We also don't need to check for circular dependencies, since those circles will break themselves as soon as one submission out of them is posted.
