sliceedit: V to toggle visible; F6 moves the view; show hidden slices in a different colour.

There is one bug (which I don't care about): using F6 in-game changes the root
slice position permanently. This is because when editing an existing slicetree
no temp 'draw_root' slice used as the root.

Added a little FindRootSlice helper.
