Sample model syntax fix

[yucombinator]

I noticed that the .glb sample model for BrainStem has an extra field ("disable":[]) in techniques.states, causing it to fail schema validation.

I don't think that field is defined anywhere in official specs (only enable is defined in v1.0), so I edited the glb file and removed it, as it was not needed anyways. The disable field is absent from other versions of the model (gltf, gltf-embedded, etc).

Good catch! disable was removed from the spec before it was finalized.

@lexaknyazev should we re-open this PR in glTF-Sample-Models since that is the future home of the sample models?

Since we're going to remove all models from this repo, PR should go straight to glTF-Sample-Models.

I'm curious, why not remove the sample models from this repo right away and provide a link to the new repo to avoid confusion and potentially diverging models?

@nehmebilal
It'll happen very-very soon (1-2 days).

[pjcozzi]

@lasalvavida could you look at this soon? It would help us with glTF 1.1.
