replace menu class when you press F1

[SanyaWaffles]

The title is a bit weird but I'm limited on space in the title.

I want there to be a way to redefine the menu that is called when you press F1. Right now it seems to be hardcoded to ReadThisMenu.

Use case: I want to code my own Readthis menu (text based rather than graphics only) and have it pull up when the user presses F1.

I know I could just rebind F1 to pull up the menu (in theory), but I was wondering if it would be too much work to just do some sort of gameinfo key to redefine what is pulled up when you press F1. If it doesn't exit all ready that is.

Would definitely prefer this too over a hacky runtime replacement using a static event handler.
