WebGLRenderer: Procedural uniforms update.

[sunag]

Basically this turns WebGLRenderer more flexible and this too is a simplification of uniforms update.

Result for tests:

All refresh material uniforms functions: refreshUniformsCommon, refreshUniformsLambert, refreshUniformsToon, refreshUniformsPhong, refreshUniformsPhysical... is replaced to refreshUniforms:

Properties identical in material and uniform are updated automatically.

In special cases, like diffuse or envMap is possible use .onUpdate to a customized update.
Uniform.onUpdate ( uniforms, material, renderer, scene )

Note that there has been a reduction in the amount of code, that would be even bigger if there were more materials.

NodeMaterial update like #18162 became possible.

Everything appears to be working in my test cases so far...

@sunag is this ticket abandoned?

With MaterialNode and new fields in materials for nodes like material.colorNode I think that we need not work more at this point for now.
