Convert RGB to 8-bit color displays as grey

If you convert Clown to 8-bit color it still displays as grey. The LUT from the plugin is getting lost due to AbstractDataViews rebuild() getting called.

Some thought about when to keep LUT is required. In this case we are changing a 3 channel image into a single channel image. It makes sense to throw away the old LUTs. Its just that the new single LUT is living inside the old LUTs when it should be elsewhere.

AbstractDatasetView handles LUTs via ResetColorTables() and UpdateLUTs(). These two methods only assign color tables associated with the view. Must somehow use the color tables associated with the Dataset. Asking for review here as to the best implementation.
