Added the feature to hide objects behind invisible objects (occlusion).
Thw workflow is:
Call context.setColorMask(false, false, false, false);
Draw the object, that shall hide other objects.
Call context.setColorMask(true, true, true, true);

The OcclusionMaterial is a ColorMaterial, that calls
context.setColorMask(false, false, false, false); in its updateMaterial method
and
context.setColorMask(true, true, true, true); in its cleanMaterial method.

Added cleanMaterial beside updateMaterial in MaterialBase.
clean Material is called in DefaultRenderer.drawRenderables

I'm not sure, whether this fits your engine.
Update:
Only OcclusionMaterial has to be added to the master, since all the magic setColorMask calls are now being done inside this class.

added mouseEnabled, mouseChildren and extra to clone
fix typo of particlePropertie's default value
Merge branch 'dev' of https://github.com/away3d/away3d-core-fp11.git into dev
Added clone method and implementations for IAnimators.
Mesh clone method now clones the animator (if it exists).
Made Mesh clone documentation clearer in regards to animation.
exposed raw buffer data from sub geometry
