[patch] Request focus in SplitWayAction window segment list

[gaben]

When splitting a way in expert mode, a window appears for selecting the segment for history reuse. If you are not satisfied with the default selection (way with most nodes), currently you need to use the mouse to change it.

After adding this line, up/down keys will also be usable without further interaction to select the way, which speeds up editing.
