Add ListBox(edge="stop"): Up/Down stop at the ends

At the first row a ListBox returns Up unhandled, and at the last row Down,
so a parent Pile moves the focus out of the list. Applications that keep
the arrow keys inside the list consume those keys in a keypress override.

- ListBox(..., edge="stop") consumes them and the focus stays in the list.
- "return" keeps the current behaviour and is the default.
- ListBox.edge can be changed later; other values raise ValueError.
- An empty ListBox returns the keys in both modes.
