-Add IsXformLinked() to determine if an xform is linked to another.
-Remove SetPaletteRefTable() and GetQRgbFromPaletteIndex() from FractoriumEmberControllerBase and its derivations, unused.
-Add FillSummary() to FractoriumEmberController. Call in Update(), UpdateXform() and other places where values are changed to force an update of the summary view.

-Remove image parameter from SetPaletteTableItem(), it was a bad design.
