Batch-insertion of many points at once using line drawing and ENTER.

Browse source 
When having drawn N new points (and having one 'free') and pressing
ENTER, the N line segments between the new points are checked one by
one for intersection with every non-grayed-out wall and a wall vertex
is inserted at every intersecting point.  This may be viewed as a
prerequisite for a 'cutter' style tool.
