Lasso needs no-snap mode

[Zverikk]

It is very hard to select a block of houses, for example, because lasso selection mode moves an object when clicked not on empty space, but near some node or way. Since the behaviour is somewhat similar to drawing mode, I propose to use Ctrl key to disable node/way selection, so a line can be started anywhere on the map.

In regular selection mode this key could help selecting rectangles starting on some way/node.

Ctrl is already used for subtracting the new selection from the existing selection.
