1176 integrate llgltfnode with selection manager and llmaniptranslate/rotate (#1258)

* #1176 Somewhat working GLTF Node support for translate tool

* #1176 Missing file from last commit

* #1176 Better translation for rotated nodes.

* #1176 Fix for objects snapping back to original position

* #1176 GLTF Samples compatibility pass -- attempt at improving rotation manip support, incidental cleanup, GLTF node debug display

* #1176 Clean out some unused and not working functions.

* #1176 Fix for mac build, incidental cleanup

* Mac build fix
