bug 1648 fixed: add the pwg_db_check_version functions for pdo-sqlite, sqlite

and pgsql, also make the $pwg_db_link global in the install_db_connect function
so that it can be used in SQLite functions.

bug fixed: with pdo-sqlite, pwg_db_num_rows always returns 0, so when
initializing user data, it tries to insert the same row twice.
