fix #177 (Slice selection broken)

two reasons:
+ no clean re-initialization after changing dimensions/dimensionelements
+ a dimension-reload forced CubeViz to ignore slice settings

For a fluent passage i added a spinner-call and reload all observations
after a slice was selected/unselected.
rework assets/cubeWithMaterializedSlices.ttl

From now on its smaller and contains only the neccessary
stuff to provide slices.
