- 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.
- Created BookChild class to share some page/chapter logic.
- Gave entities the power to generate their own permissions and slugs.
- Moved bits out of BaseController constructor since it was overly
sticky.
- Moved slug generation logic into its own class.
- Created a facade for permissions due to high use.
- Fixed failing test issues from last commits
