WebGLDeferredRenderer: added antialias constructor parameter.

This mirrors WebGLRenderer: when "antialias = true" FXAA is enabled, by default it's disabled.

Unlike WebGLRenderer though antialiasing can be enabled / disabled in runtime:

renderer.setAntialias( true );
renderer.setAntialias( false );
