Defines BeginWayAction as including node creation and way creation. When the second last node gets undone, the BWA gets split apart and the node creation is preserved, but repackaged as a CreatePOIAction. Ugh.
Turned out to be pretty hard to come up with a clean solution because the way is created before the user has chosen where the second node goes etc. Anyway, it works.

I have a branch to test this and looking at it properly is my next todo. :) |

This fixes the funniness around undo/redo for creating new ways:
"Click two or more points (=n) on map - a way connecting clicked points is being created. After (n-1) Undo's the way is gone, but the initial point still remains visible (a green dot) and the Undo button is already grayed out - one step got forgot.
It is possible to delete the point manually (red (x) button), but it should be also deleted by the n-th Undo."
My head hurts now. In an ideal world I would have squashed the three commits into one. I tried that, but Git growled at me and threatened to take my work and never give it back, so we compromised.
