HoeDown Minigame

Sets up and runs a minigame.

HoeDown is a real time area capture minigame played by 2 teams, one team trying to till as much ground as possible, the other trying to untill the ground.

DO NOT PLAY THIS ON A FARM YOU WANT TO KEEP.  YOU WILL WANT TO MAKE A NEW SAVE TO PLAY THIS MINIGAME ON.

The host player controls the game.
F5 refreshes the farm ready for a new round
F6 begins a countdown to start the game.
F7 toggles game mode (can only enter game mode if a game is active, including countdown).

Refreshing the farm involves removing all objects/weeds/grass/trees from the farm, and setting up an arena.  The location and dimensions of the arena can be configured in the config file.  This will also replace the inventory of every farmer with a How, a Pickaxe, a Red Cowboy Hat and a Blue Cowboy Hat.

While the game is active, there is a window displayed in the top left corner showing how long is left in the game, and the current score (tilled vs untilled).
When the game finishes, the final score is sent in the multiplayer chat window.

There is an option in the config file to activate Enclosing Tiles.  When this is active, completely surrounding an area with tilled/untilled ground will fill the enclosed area with tilled/untilled ground.  i.e. box in an area to capture it.  Diagonals don't count.  This is only active while a game is active.

  "X": 31,					- The x location of the top left spot in the arena (not counting fences).
  "Y": 26,					- The y location of the top left spot in the arena (not counting fences).
  "Width": 20,				- The width of the arena (not counting fences).

  "GameTimer": 60000,		- The length of the game (in milliseconds).
  "EncloseTiles": true,		- Whether fully surrouding an area with tilled/untilled ground should fill the enclosed area.
