implemented Local::Utils dump_query function, and a package (App::DB::Result) to overload DBIx::Simple::Result, but its functions are not available to App::DBIx, possibly due to Feature::Compat::Class limitations

added checks for test plain-text password in config; documented data import/export for sqlite3

added check for upload path for test file

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
