upgrading phpMyAdmin

do not overwrite, only copy config.inc.php from old version, grant priveleges to pma-user

Do not overwrite the old directory - better rename it and create a new phpmyadmin, only copy config.inc.php from old version. If the phpmyadmin-database is not configured properly (warning on start screen): follow instructions and create it, create pma-user with CREATE USER 'pma'@'localhost' and grant priveleges to pma-user with GRANT ALL PRIVILEGES ON * . * TO 'pma'@'localhost';
