Remove ray antialiasing.

Previously, rays were always cut short at corners: If a ray really
went like
.....
@**..
..***
.....
it was cut short (for find_ray/targetting/shooting purposes) to
.....
@*...
..***
.....
Note that a wall at the removed cell would still block the given
ray!

This makes ray footprint length matter, so rays are sorted to
prefer those that pass through fewer cells.

However, this gives quite a few ugly beams, in particular around
corners.
