Updated Closure compiler. Added more verbose compile warnings. Fixed all compile warnings. Started to fix runtime warnings in examples.

For verbose compile warnings to be practical I had to add externs and disable some warnings manually (there were tons of complains about "global this" and "cannot instantiate non-constructor"). Other solution would be to annotate explicitly constructors all over the code base.

(prompted by John Carmack's praise of static code analysis http://altdevblogaday.com/2011/12/24/static-code-analysis/)

Also moved `.overdraw` to Material.
Code is much simpler now :)

Also replaced WaltHead.js (old format) with WaltHeadLo.js (new format)

Got stuck on the PathCamera/PathControls one. Maybe it's time to rewrite this...

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

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?

Webgl examples next.

Renamed examples.

Need to test this on IE9... :)_

Implemented material blendings (THREE.NormalBlending, THREE.AdditiveBlending, THREE.SubtractiveBlending) in CanvasRenderer
Added MeshNormalMaterial (per face)
