[Feature Request] Sharing and copying links should let you copy a local instance link as well

The current behaviour is correct, as the remote instance is the canonical source, but being able to copy/share a link to your home instance would be nice as well.

Use case: maybe the comment is coming from an instance that is down, or one that you don't necessarily want to link to.

If the user has more than one account, being able to select which would be nice as well, so maybe a submenu or per account or a global setting.
