#1126 gltf scene import prototype (#1172)

* #1126 GLTF Scene import initial prototype (working geometry import for some assets)

* #1126 WIP -- Expand support for more vertex formats, PoC material import, shadow support, scale support

* #1126 move GLTF implementation to newview/gltf

* #1126 Refactor attribute loading to be less copy/pasta for each combination of types

* #1126 Partially working object selection.  Ability to have multiple scenes at once.  Helpful message on how to use the preview button.

* #1126 Add bounding box debug display and untangle GLTF raycast from LLVOVolume raycast

* #1126 Working raycast on GLTF scenes.

* #1126 Remove some #pragma optimize offs
