2020-01-26 changed infolabels

- ListItem.Art(thumb) / Player.Art(thumb)
these infolabels will no longer fallback to 'poster' or 'banner' when no 'thumb' is available.

- ListItem.Icon / Player.Icon
since 'icon' wil display the 'thumb' when available (and fallback to the DefaultIcon),
these infolabels are also affected by the changes above.
