VTK volume rendering.

  classification GUI to add 3D rendering options.
hardened volumina: more asserts agains malformed lazyflow requests
for colortable source, accept QColor color tables as well
colortables: added a colortable with 256 random colors
LazyflowRequest got name property for debugging
