Due to differenced redraw, midpoint.ways was getting stale, so sometimes dragging a midpoint didn't add the new node to all ways. Better to calculate participating ways when needed. This also simplifies the code for adding a midpoint via double click. It does make filtering midpoints on redraw a bit more expensive, but a cursory profile didn't show it being a problem. Fixes #763.
