Modification of #2145

Original PR broke class-type visibility toggles in the editor, so this adjustment on the same setup keeps the optimized path, but also enables the original class-based render toggle if the editor is open.
(Also adds TORQUE_TOOLS check to have it be even leaner if the project doesn't have tool support at all)
