Make tab switch between path element and listing, not between listings

Do note the big fat comment.

I'm actually pretty happy with this commit. I think there's a fair
chance that this is the right behavior, and it simplifies a fair amount
of code, e.g. getting rid of manually setting curIndex on this.form and
restoring selection after Dialog.close() (that's handled by tui-lib
now). It also discards the "hack" I had to do to make the AppElement
form capture keyboard input in the first place. (I had to use addChild
with the container paneLeft/paneRight elements so that keyboard input on
their children, which are the inputs of the AppElement form, could be
captured.)
