Merging with alteredq's branch.

Also some fixes along the way to properly handle vertex colors in loaders.

Many things still broken, but we move forward.

Not tested yet, as the rest of the engine doesn't work yet.

Not sure about Firefox 4/Opera compatibility...

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

Added geometries example (need to add Lathe one).
Fixed Cylinder.

Enabled by "useConstantSpeed" parameter.

This is done by creating new spline which resamples original spline proportionally to linear-piece-wise integrated length of segments of the original spline.

It's not perfect, but speed-wise it should be better, especially when the original spline has very different lengths of segments.

New spline may have a bit different shape though (Catmull-Rom spline guarantees that it will pass through control points, but with more dense control points it may get kinks in between). You may control density of resampling by "resamplingCoef" parameter of the PathCamera.

No more need for manual update hack.

Problems with keeping constant speed are still there. Added debug particles sampled along the spline - seems problems come from spline, samples have weird distribution.

Thanks to empaempa for the fix.

PathCamera automatically follows path passing through waypoints (interpolated via Catmull-Rom spline). View angles can be constrained and controlled by mouse.

Work in progress, there are still some issued to be solved (constant movement speed, broken automatic update, broken frustum culling).

It's now possible to create fog with zero density (which makes sense if you want to build shader with fog support, but not yet use fog, in contrast to not having fog in scene at all).

These are stored in "material.map.sourceFile".

Texture sets needsUpdate to true for <canvas> elements by default (webgl_objconvert_test.html seems to be randomly affected by this).

Also updated GUI-DAT (didn't help with recent Chrome compositing bugs, though this is Chrome Windows issue), added FileAPI to Detector and fixed aspect ratio bug in WebGLRenderer.

Thanks to empaempa for spotting this ;)

If no object is passed to initMaterials (for example, if material is pre-built while loading, or shader program is intended for sharing), max limit of 50 bones is used (should be enough to leave space for other uniforms not to hit ANGLE limits).

Clearing API for rendering to RenderTarget is now flipped: before forced clearing of render target was default, now no clearing is default.

New way of doing things saves one extra duplicitous clear call when switching render targets (like when doing postprocessing).

(doing documentation is indeed turning out to be useful)

Added some examples to README.

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

Next: Object3D::translate...

WebGLRenderer checks if texture is power of 2. Throws an error if it's not.
