Fix scene-viewer.py for use under MacOSX with a Mac App.

User should compile scene-viewer-macosx.app and copy it from the Xcode DerivedData
folder into the top-level scene-viewer source directory.  Then install the Blender
add-on and configure:

Encoder path: /path/to/gameplay-encoder
Viewer path: /path/to/scene-viewer-macosx.app  (doesn't matter if there is trailing /)
Workspace: (leave blank)
use the given .blend filename

Fix scene-viewer.py for use under MacOSX with a Mac App.
revert back to fwd Y up Z
use the blender scene filename instead of just 'scene'
removed the logo signature
added git attributes file to handle crlf
normalized line endings
moved utilities to a seperate file
* added couple of tests to avoid crashes
* changed scene_viewer.material's shaders so grid have colors
Added Rotate X checkbox.
If checked and Preview, script rotates scene around x -90 (and rotates it back after exporting) so node->rotateY(ang); works right.
If used, no instances anymore. Preview only when in Object-mode.
