• improved and added some log messages

• fixed a bug where mysql_escape_string didn't set the destination var to empty if the source variable was empty
• fixed a bug where the HTML logging logged every callback even if there wasn't any log message in it
• fixed a bug where the plugin entered an infinite loop while calling mysql_close with the wait parameter activated
