One of the things that has been annoying me for a long while. Previously the entire map would be revealed immediately upon load (same for subsequent floors) and make it practically a juke the enemies while you dash for the stairs simulator. This is partially affected by the lack of map RNG (implemented, not wired up) but I think the map being loaded in its entirety was a huge downside for how engaging the game was.

This implements a Fog of War, where you have a relatively small vision distance (TODO: let items and character stats affect this) and improved the enemy AI to stop chasing you all the way from China while you are a humble fisherman in Spain. Most notably:

can_see_player() now uses actual LOS + range (was only adjacent check)
Enemies only chase when player is visible
When player not visible, enemies patrol randomly (30% chance to move)

This comes with changes to vision where you can only see 8 tiles in all directions (with wall occlusion) while nemies can see 6 tiles. As I said, enemies won't chase through walls but they do patrol when player is hidden. Unexplored areas are completely dark; previously seen areas remain slightly obfuscated to allow wasting screen free estate. You cannot see enemies in previously explored rooms.

The vision range is a little different for enemies. For now I've elected to make enemy vision slightly less than the player character but that might make it too easy to avoid enemies (Goblin=7, Skeleton=6, Orc=5). To combat this, I've made enemies track alert state and last known player position to "rally" nearby enemies by propagating alert to create a "search party" effect.
