This is an experimental attempt at selecting more intuitive beams for

targeting (see 1725723):
- The default beam selected for targeting is the shortest available beam
  that is closest to the Bresenham line between src->targ.
- Targeting beams convert aliased perpendiculars into diagonals, which
  look better. This requires an immortal fudge to make sure the diagonal
  conversion doesn't happen at the wrong places (when the conversion
  would cause the beam to miss the target square).
- Tweaked beam bounce behaviour to look more natural.

Comments and suggestions welcome.
