Algorithmic Directional Lighting (#1726)

This is similar to #1722, but it uses a bit of math to allow explicit setting of the angle of light.
Pretty much complete, although no lights have been updated to use directional lighting.

Features:
Facing a wall with a directional light results in darkness - light is not emitted on own tile.
