config.php : support switching to sqlite; default to sqlite (autocreates db in system temp dir); see issue #29
See #29 - missing  (php/properties/access_change_template.php)
at least do something on an error condition
get the right parameters (user creation; website_code/php/user_library.php) see #29
fix queries/variable assignment
fix include path so dont_show_template() works
sqlite database_functions variant
