Sorry that you had to add it @alteredq.

This should be the last one. The only ones left should be "webgl_postprocessing" and "webgl_postprocessing_dof" where I got stuck.

Useful for tracking WebGL API calls overhead.

As per discussion in https://github.com/mrdoob/three.js/commit/08a37d34c16d3ccd19191251edd945be62a9f3e8

Scene graph update is fast enough that on my system there is no change of FPS when removing the matrixAutoUpdate = false stuff.
Also compared with r48 and FPS went from 12fps to 20fps :D

Except special cases like 3d renderers and cube cameras all examples should be now without warnings.

All should now work with new cameras.

Implemented .autoClearColor .autoClearDepth .autoClearStencil as per @alteredq's suggestion at #587.

* Camera.useTarget is now false by default. Updated some of the examples. I tried to remove target altogether (and use lookAt every frame), but I found that WebGLRenderer's ShadowMaps uses a camera with target. Will try again at some point.
* Object3D.lookAt now checks if it's a Camera and does the inverted view.
* Quaternion glitch reported at #595
* Added .name to Material
* WebGLRenderer .clear() to .clear( color, depth, stencil ). All of them true by default.

Updated build script.

Also cleaned up examples from individual includes, only sandboxes and ubiquity now include individual files.

Added translate( distance, axis ), translateX( distance ), translateY( distance ) and translateZ( distance ) methods to Object3D.
Camera3D translate method overrides Object3D's one. NoFly parameter removed (this should be handled from outside I think).

Object3D::lookAt works! (and Vector3.setRotationFromMatrix too!)

Next: Object3D::translate...

Added RequestAnimationFrame system to the new examples.
