Added general/any_object module, any_object_prototype.h and any_object_definition.h for defining ANY_OBJECTs for arbitrary types. Currently only Cell_component is instantiated in this manner. Added select_tool and any_object_selection for graphical selection capability. Scene_objects may now be given a "represented object" = an Any_object which can be picked from them.
