[flexcoders] Avoid using skin applied to my app

[Bron Davies]

I have a set of css files that skin my flex app by dynamically loading 
the compiled swf using something like StyleManager.loadStyleDeclarations
("mychrome.swf").  However I have some third party SWCs that are 
referenced and the skin is being applied to those as well but I don't 
want it too.  I can recompile the SWCs if needed but I don't want the 
skin to be applied to SWCs that show UI. How can I do that?
