This was making mess for non-square textures.

Doing this in multiple steps not to confuse git.

Now that the new version of UTF8 supports materials, we may as well use them.

See #2399

See #2336

Fixed ColladaLoader to create appropriate materials. Updated monster DAE to look better with phong shading.

Seems horse model was wrong, it had one extra frame at the end (almost identical to the first frame), which caused our animation playback code to be incorrect in order to accommodate for this.

Side-effect was that two frame animations were completely broken.

Bah.

MD2Character is an object encapsulating character body, multiple weapons and multiple skins as a single entity.

Fixed Blender importer to work with Blender 2.60, add option for importing workers or non-worker models.

Fixed more examples to use worker-less format. All examples should work now.

Only Max exporter should be left to change.

Work-in-progress => do not merge yet.

OBJ converter, JSONLoader, BinaryLoader and some examples are done. Still need to do Blender exporter, SceneLoader and more examples.

Advantages:

- faster parse times
- bypass array initializer size limit in Firefox
- no more crashes in Chrome 15 (caused by too many concurrently active workers)

Disadvantages:

- more browser UI freezing
- multiple models tend to appear all at once with the last one (instead of popping up progressively)
