*
* KR.Helpers.gainRandomItem(array)
* This method takes an array of items that you wish to pool from.
* After that it will return an item to the player.
* 
* Example: KR.Helpers.gainRandomItem(['weapon', 1, 'item', 1, 'item', 2]);
* These are case sensitive and refer to the type of item you want the player
* to gain.
* 
* KR.Helpers.setItemGainAmount(Number)
* This method takes a number, which is used to set the amount of the item
* you gain from the game.
* 
* Example: KR.Helpers.setItemGainAmount(2);
* This would set the gain amount permanently to 2 until the game is restarted.
* If you want to return it to 1, just say KR.Helpers.setItemGainAmount(1);
*
* Tip: You can also set a random Item gain like so:
* KR.Helpers.setItemGainAmount(KR.Helpers.randomNumber(1, 3));
* You'll get 1 - 3 as the number of items gained.
