Many changes to GL rendering backend.

- Added WebGLSpriteBatch which is more generic/modular and can even be used without stage/etc.
- Removed unnecessary init of a WebGLBatch from WebGLRenderer constructor
- Moved all the extras rendering from WebGLRenderGroup to WebGLExtras
- CustomRenderable was not getting initialized, so I fixed that in WebGLExtras
- CustomRenderable was getting called with WebGLRenderGroup as first param, instead of WebGLRenderer. Fixed now.
	However, in order to facilitate this fix, we now pass the WebGLRenderer
	to WebGLRenderGroup when rendering. We also pass the renderer to WebGLGraphics for easier
	migration to multiple GL contexts in future.
	 	(This also affects WebGLRenderGroup.renderSpecific)
rendering working with new batcher
