fixes #2666

Up to 95 fps.

Small performance improvement (88 fps => 91 fps).

Much faster with "discard" (56 fps => 88 fps).

Also fixed light colors to be in linear color space to match the rest of the pipeline.

- changed model to Lee Perry
- changed light pass material to use RGB-weighted wrap-around lighting (with deferred can't have easily together multiple material types :S)
- changed deferred rendering to use linear space lighting

Refactored deferred rendering example to make it easier to use per-object depth and normal materials.

This is to make it work with textured objects that use Geometry (instead of BufferGeometry). Otherwise reusing the same Geometry between color and normal passes creates buffer requirements clash, where one pass needs just normals and other just UVs.

ShaderMaterial forces creation of normal and uv buffers all the time (MeshBasicMaterial just creates what's needed for the first render).

Goes with #2657

Removed internal variables _projectionMatrixArray and _viewMatrixArray from WebGLRenderer and render plugins.

These are not needed anymore as matrix elements are directly usable for uniforms.

Unfortunately we can't keep these settings always on: without "--jscomp_off=checkTypes" the amount of spam is just too crazy. It complains about tons of normal things, I had to manually dig out few useful warnings among 900 irrelevant ones.

Trying to find out why we miss warning about trailing commas (see #2665)

Deferred rendering doesn't play well with transparency.

- made it work with r54dev
- cleaned up formatting
- fixed light pass not actually moving light proxies (there is less overdraw but lights now can get culled sometimes, need to fix this)
- changed high-def Walt to be UTF8 model
- made geometry passes work with hierarchies

See #2624

Allow non-indexed BufferGeometries to render the entire buffer in a single draw call rather than a draw call per 2^16-1 vetexes

build.py to build sourcemaps according to output file. (eg. three-custom.js.map for three-custom.js)

- add --sourcemaps flag to build.py
- see #2465
- node.js build script could support sourcemaps with uglifyjs2

Renamed SpriteMaterial properties: affectedByDistance => sizeAttenuation, mergeWith3D => depthTest. Added support for SpriteMaterial.depthWrite.

SpriteMaterial should be now more consistent with other materials.
