[Fixed] .dae Export

Hi IStonia,

When exporting a scene to .dae(collada), Nvil is exporting the "Rootnode" as a "Joint", when I believe it should be a "Node" (see pic)
That is causing issue in some applications (ie: Blender) that attempt to import the file, as it create`s joints(bones) instead of the geometry.

Changing "Joint" to "Node" allows all applications I have tried to import the file correctly.

Please check when you have time.

Fixed.
