Fix wrong default title for UPNP files

Hi Michell,
i have added new files from an UPNP Device. If the App failed to identify some Movies the Title of this Movies is extracted from the filepath in the BaseMovie-Class. The Problem is that the filepath of the UPNP-File is something complete different than the actual filename. 

In Example:
BaseMove-Class try to extract the title from the filepath e.g.: 
doku/Too Young To Die - Kurt Cobain (12.07.21_arte)\<MiZ\>http://192.168.1.10:50002/v/NDLNA/4504.avi
So the extracted title will be "4504".

To Fix this i extracted the title from the real filename instead of the UPNP-filepath.

regards,
David
