Letting external plugins deactivate TSVN menus? I don't think so. We'd
have to deal with users reporting bugs to us which are not TSVN bugs at all.

The problem with that approach is that we're dealing here with shell
extensions. One bug would crash the desktop.
I don't like to take that risk.

Such plugins would have to be COM-objects and implement an interface we
would have to design ourselves. But then it may be easier for you to
just implement your own shell context menu handler.
