Target Data in C1

Nothing yet -- I've been focused more on sorting out C2 so far because it's better documented, and because I still only have the barest understanding of how the window system works. (I still have no idea for sure where the new abilities are going to /go/, only that I'm fairly certain I'll be freeing up enough space by getting rid of, say, Slot and Rage.)

At the very least, I think I've found code that'll work re: targeting by grabbing it from the original MenuBlitz patch (by... Ronnen, IIRC) that LightPhoenix derived their patch from in the first place! So we'll see how that works out when I get around to testing.
