Merge branch 'reproducible_dungeon_layouts' into unnethack

The RNG is seeded with a seed determined at the begin of the game.

Use OPTIONS=seed:number to get reproducible dungeon layouts.

Dungeon layouts should always be the same with the same seed.

Objects could vary with regards to artifact but otherwise should be the same.

Monsters vary by player experience level, race, and role.

The game's seed is written to the dumplog.
