changed how DPW model handles file upload functions for checking and setting upload directory: * moved duplicate code for checking existance of uploaded file into discrete function * initialised '_upload_dir' value as a param during file check function to avoid requierement for duplication in route and model; put rudimentary date check on sqlite3 db (still permits invalid dates); new test files

docs_path is now a field with set_docs_path() method to streamline save_document()

added filter function for household summary page

changed household documents path to ~/Documents/docs-lib for backup reasons due to impending directory size (maybe Moongate to follow)

moved file save function from DPW route to model; function creates new sub-directory for file if it doesn't exist

provide session object to tt for use with debugging premature session expiry; provide redirect for requests without trailing slash (instead of receiving 404 page)

moved dpw categories from tt into db

extended app to provide household/dpw function; provided session expiry time display; increased dev env cookie_duration (but session still times out too early); sync'd InfoLib & Moongate save_document() methods with DPW class (using global @cols)

major rewrite - combined separate docs-lib and moongate apps into single app using prefixes with multiple route files; merged DB functions into model which is now a D2 plugin, providing encapsulated model domains (infolib, moongate & dpw); uses route names to allow tt to call uri_for_route, but some caveats: * route names must be unique across all route files * uri_for_route cannot be used in any template loaded after a forward since the data required in request.uri_for_route($name) is deleted during the forwarding process leading to fatal error when tt calls the uri_for_route function; META function no longer works since tt WRAPPER function disabled to allow routes to define layout
