pgraph: fix some TextureAttrib state cache issues

Browse Source 
The _render_stages and _render_ff_stages cannot simply be copied, because they contain pointer references to the previous TextureAttrib.  Never copy them, and always mark _sort_seq as stale.

This fixes a test failure in replace_texture.
