[Feature Request] Discoverable and Collaborative Shared Collections

[frank20a]

Sharing collections was mentioned in #316 and currently works but they are not discoverable by different users (you need to share the link) and other users cannot contribute to the collection, only view it. It would be great to have collections that show up on every (or chosen) users home and everyone contribute by adding/changing/removing items. Same goes for templates/scrapers/tags/etc. they could be shared among users.
