51243: Handle Player Legs
Used by the routine at HandleHumanLegs.
Does all of the work for the player, as the top half of the player is only a copy of the bottom half placed above it (see HandleHumanTop). If the player has been killed this starts the death sparkles. Otherwise it reads the controls, lets the player pick up or drop an object, turn, jump and walk, and then moves the player.
