Add property group widget for molecule representation

expose some mapper parameters:
 - atoms/bonds visiblity,
 - radius values/scale/type

presets are also available from proxy

+# improve-molecule-represenation
+
+* Expose molecule mapper parameters, such as atom/bond size and color, on the molecule representation.
+* Add predefined presets to control those parameters. Presets and parameters are available from the GUI
+  and from python.
