Allow filtering to only include visible tags #590
Description
Expected Behavior
view(tag='foo',tags_hidden=False) should exclude entries where they have a tag of foo but where the tag is hidden.
category.tags should also grow this ability.
Context
on https://sockpuppet.band/releases/ it'd be nice to be able to show only the albums which express a particular genre tag rather than ones which contain a tag, and make it a toggle.
