[Feature] Add 'Scene edits' view on the studio pages

[kronkels]

Is your feature request related to a problem?
Currently it is not possible to view edits made to scenes belonging to a given studio. This would be a useful feature for moderation.

Describe the solution you'd like
There are three tabs on the studio page right now. 'Scenes', 'Links' and 'Edits'. I'd suggest to rename the 'Edits' tab into 'Studio edits', and add a 'Scene edits' tab that returns a feed with edits to the scenes within that studio.

An alternative would be to add 'Scenes' and 'All' (default) to the 'Type' dropdown on the 'Edits' page.

Same for performer pages, to see scene edits that involve the performer being viewed - edits that remove or add them to scenes.

Basic query that returns edits than contain a performer ID $1:

SELECT id FROM edits WHERE
	target_type = 'SCENE' AND (
		jsonb_path_query_array("data", '$.new_data.added_performers[*].performer_id')
		|| jsonb_path_query_array("data", '$.new_data.removed_performers[*].performer_id')
	) ? $1;

Update: prototyped, but not finished
