C0BE: Handle Player Legs
The handler for the lower half of the robot while it is walking (objects 10 to 17). The upper half of the player is only a copy of this one placed above it (see HandlePlayerTop), so this routine does all of the work for the player. If the player has been killed it is turned into a sparkle. Otherwise the input is read, the pickup and drop, turning, jumping and walking are dealt with, and the player is moved. While the player is outside the room (walking through an exit) it can fall but is not allowed to rise.
