* Started mass-refactoring of the current entity repos * Rewrote book tree logic - Now does two simple queries instead of one really complex one. - Extracted logic into its own class. - Remove model-level akward union field listing. - Logic now more readable than being large separate query and compilation functions. * Extracted and split book sort logic * Finished up Book controller/repo organisation * Refactored bookshelves controllers and repo parts * Fixed issues found via phpunit * Refactored Chapter controller * Updated Chapter export controller * Started Page controller/repo refactor * Refactored another chunk of PageController * Completed initial pagecontroller refactor pass * Fixed tests and continued reduction of old repos * Removed old page remove and further reduced entity repo * Removed old entity repo, split out page controller * Ran phpcbf and split out some page content methods * Tidied up some EntityProvider elements * Fixed issued caused by viewservice change
