[Krypton] ListItem.Property(WatchedEpisodes) passing empty string

If a show has 0 watched epsiodes, then it should pass '0' rather than an empty string?

This messes up int(xbmc.getInfoLabel('ListItem.Property(WatchedEpisodes)')) for instance, as an error check has to be added to catch ''.

Also, the property doesn't get updated until you move off and back onto item, bit annoying
