Admin functions do not accept URL encoded values
The admin functions should accept/decode the mount GET value since / is a reserved character.
This works: http://192.168.1.10:8000/admin/metadata?mount=/mystream&mode=updinfo&song=ACDC+Back+In+Black
This doesn't: http://192.168.1.10:8000/admin/metadata?mount=%F2mystream&mode=updinfo&song=ACDC+Back+In+Black
Response is: 400 - Source does not exist
