- 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.
Phasing out the view service from being a generic 'service' class,
moving the core create/delete methods into the model.
The idea is that the existing query work will need to interlink
with the favourite system so maybe we have a (or many composable)
query building classes rather than mixing query building and
create/delete work as per the old service.
