Catch itunes duration parsing exceptions

Browse source 
Parsing of a malformed or empty duration resulted in an uncaught
exception that was breaking feed parsing completely. We already catch
exceptions when parsing other fields, e.g. href attribute of the image
tag. Also, it's more user-friendly to handle malformed data instead of
failing everything.
