General Pep8 cleanup Removed unused variables and imports Removed a panel from add_empty_as_parent Standardized the property definitions across all the scripts Moved scene props from third_domes_panel_271 to init for proper removal Added a Enum prop for mesh type in teapot Fixed a small issue with Geodesic domes self.reports (problem with value fields message spam) Fixed props names in Geodesic domes Consistent tooltips Reorganized menus: Mechanical Menu including Pipe joints, Mesh gear Added separators
