closes #2896 - move default options / custom code into model functions - move most of the filtering logic into base/utils.filtering (to be relocated) - move the remainder of findPage back into base/index.js and remove from posts/users&tags - move pagination-specific logic to a separate 'plugin' file - pagination provides new fetchPage function, similar to fetchAll but handling pagination - findPage model method uses fetchPage - plugin is fully unit-tested and documented
