Allow skins to provide a "dpad-rotation" field for each layout.

This is used to deal with the fact that the framework *always* assumes that
the physical DPad is rotated in landscaped mode, while the default skin no
longer does that.

NOTE: tested on old skin files for backwards compatibility.

(Upcoming skin fixes coming in another patch)
