Bumped version to 2.4.2 Pep8 cleanup Moved scene properties to a property group access it through context.scene.auto_mirror remove the properties upon unregister Add poll checks for Mesh objects to operators Add missing operator description Remove the draw function from the AutoMirror operator since it is not used and enabling Undo will not work in this case, since depending on the initial settings it can produce unwanted results
