fix(nif): leave out a root node's rotation and translation

Browse Source 
The client's render component sets the object's own position and
rotation on the root node it loads, over the stored ones, so a root's
turn never shows in game (its scale stays). NifFile now reads roots the
same way. LU Toolbox's .nif (root turned 90 degrees about X, the
NiLODNodes turned back) now stands up in icons and the dashboard's
views; every game .nif has an unturned root and reads as before.
