Move Sprint saves into $SAVEDIR/sprint.

This allows the same character name to have ongoing Crawl and Sprint games
without filename collisions. I'm using a subdirectory instead of a filename
suffix (such as Foo-501-spr.chr) to avoid blowing DOS compatibility.

Add GAME_TYPE_UNSPECIFIED as the uninitialised game_type. It's synonymous with
GAME_TYPE_NORMAL, but allows the code to distinguish between a player having
chosen the main game and the player not having made a choice yet.

get_savefile_directory() returns the current savefile directory based on game
type. Direct use of Options.save_dir should be avoided in new code.

player_save_info now tracks game type as well.
