Still needs to be done: canvas renderer / picking / canvas examples.

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

(Phewww!) I'm sure there are still things I missed...

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

Found out that CrosseyedWebGLRenderer probably wouldn't work for target-less cameras.
Something weird going on with `webgl_scene_test.html` and `webgl_scene_test_blender.html`. For some reason cubes dissapear.

Masking was real pain to get working with multiple render targets :/.

Unfortunately this introduced dependencies on MaskPass.js and ShaderPass.js even for use cases that do not use masking. Bah, will need to figure out some better way for deployment.

Added generic ShaderPass. Removed SepiaPass, ScreenPass, VignettePass. Added bleachbypass shader. Simplified multi-composer pipeline in postprocessing example.

Not sure yet about names and location of files.

Modified examples to use it, hacking projection matrix started to feel a bit dirty.

WebGLRenderer antialias is off by default (considering Firefox doesn't support it...)
Formatting clean up here and there

In most cases RGB format is enough (RGBA is needed for example for lens flares to work ok with postprocessing).

Interestingly here performance doesn't seem to be affected.

Moved materials/RenderTarget.js ⟶ renderer/WebGLRenderTarget.js

It doesn't have effect there anyway as scene is rendered to FBO without multisampling.

Turning antialiasing off here didn't have much effect on performance though (unlike for particles).

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.

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)

Refactored everything to use CamelCase naming for properties. Plus some smaller fixes here and there.

Went through all examples, all should work.

JSON files exported from Blender / converted from OBJ files still use underscored property names internally. I don't know, should these also be changed?

Object3D::globalMatrix ⟶ Object3D::matrixWorld

Added hierarchy examples.

	build/Three.js - Includes all renderers + extras
	build/custom/ThreeCanvas.js - Canvas renderer only
	build/custom/ThreeDOM.js - DOM renderer only
	build/custom/ThreeSVG.js - SVG renderer only
	build/custom/ThreeWebGL.js - WebGL renderer only
	build/custom/ThreeExtras.js - Extras only

Moved `THREE.Detector.js` to `examples/js/Detector.js`.

Updated examples to reflect these changes.
