Revamped some complex queries, added favourites to home

- Removed old view system and started use of new query classes instead.
- Finished off RelationMultiModelQuery but found it was less efficient
than x-many queries due to the amount of tables being scanned.
Adding now for history but will delete as not used.
- Updated recently viewed to use same query system as popular items
  rather than running and joining x-entities queries.
- Added "Most Viewed Faviourites" listing to homepages.
