Subject: [PATCH] The addon is updated for Eevee/Cycles - part 1: the atoms get
now a useful color by using nodes (material properties). The color used in
the viewport shading ('solid mode') has been removed since it doesn't make
sense anymore. Otherwise one always has to manually choose 'using nodes' in
the material properties.
