Implementation of custom python entries in all right click menus

Browse Source 
Hi Guys,

as one of my clients needs the possibility to have custom menu entries in the general right click menu (all over Blender: in the node editor, properties, toolbars,..) I talked with Campbell about expanding our hard coded menu a bit. This is the outcome. As I only need those two, I support currently a button_prop and a button_pointer.

{F540397}

I tested the changes with a custom script where I added a custom entry and executed an operator on click - it seems to work exactly how it's intended to. The script: {F540435}

As I'm not too experienced in rna stuff I would really appreciate any review.
Thanks very much Campbell for his open ears & help on this issue!
