Extended PlayListPlayer to call g_player with media type to prevent false audio/video detection by file extension only
Mantis #3728

Added a check for the existence of MediaPortal.xml in CreateTemporaryConfiguration. When not found Watchdog.exe will start Configuration.exe in Wizard mode, wait for configuration to be completed and restarts the Watchdog App.
