Can't load exported Manuel Bastioni Lab 1.2.0 json model with shapekey directly

[akjava]

There are three.js-issue (Morph targets vertices array in Blender exporter wrong)
mrdoob/three.js#7724

Manuel Bastioni Lab 1.2.0 json model with shape-key/morphtargets can't load correctly on three.js-r74(I'm not sure newer version fixed it or not.)

I think there are another problem.morphtarget vertex turned need fix like this
vec.applyAxisAngle( HREE.Vector3( 1, 0, 0 ), THREEMath.degToRad( -90 ) );

There are function to convert/fix these json model.how ever ModelWeight can't read directly.

because it's detect loaded file is either format3 or format4 and return json-model.
but Mbl3dLoader(fixing class) is not support json.

I'm still considering how to integrate these.
