1.10.0 missing %root% parameter in images player parameter list (1 Viewer)

[killer8]

In the mediaportal configuration there is a button list in DVD Discs/Images -> DVD Discs/Images Player -> External player -> Parameters. To use Total media theatre to play bluray etc, %root% should be used as parameter but this parameter is missing from the list which is shown when you click the "List" button. I think this should be added since it's not clear now the parameter is available and it took me quite some searching to find it again.
