  @description
  Simple hack for changing avatar to another sprite as you move between rooms.
  
  HOW TO USE:
  1. Copy-paste into a script tag after the bitsy source
  2. Edit hackOptions below to set up the avatar list for rooms you move through.
  
  By default, the avatar will reset to the default if you enter a room without a sprite defined.
  This can also be changed in the hackOptions below to instead apply avatar changes permanently.

  	// You need to put an entry in this list for every room ID or name that you want to change the avatar,
  	// and then specify the sprite ID or name of what to change to. Expand this list to as many rooms as you need.
  	avatarByRoom: {
  		// Note: the entries below are examples that should be removed and replaced with your own room -> sprite mappings
  		0: 'sprite ID',
  		1: 'A', // note that 'A' is the player sprite, so this does nothing by default, but will reset the player if permanent == true
  		2: 'another sprite ID',
  		h: 'a sprite ID for a room with a non-numeric ID',
  		'my room': 'a sprite ID for a room with a user-defined name',
