Changes the export of animations; puts each object into a wrapping <animation>-element, so all samplers for an object are grouped in an animation hierarchy.

So, an export of armatures "Armature" and "Armature.001" would be:

<animation id="Armature-anim">
__ <animation id="Armature_Bone_pose_matrix"> ...
__<animation id="Armature_Bone_001_pose_matrix"> ...
...
</animation>

<animation id="Armature_001-anim">
__ <animation id="Armature_001_Bone_pose_matrix"> ...
__<animation id="Armature_001_Bone_001_pose_matrix"> ...
...
</animation>
