* Development 15 | Beta 0 | Development 1 | Experimental 1 *

* Added Tile2D
* Added the tileSize variable in the constructor of TileMap2D
* Added the startYvariable in the constructor of TileMap2D
* Added a lot of variables and a few methods in KeyboardInput

* Changed the type of the 'tiles' array in TileMap2D to be Tile2D

* Fixed bug: GUISlider wasn't sliding properly
* Fixed bug: Spelling mistake when writing Settings config, this
prevented the setting of the MusicVolume setting (MusicVolument)
* Fixed bug: MusicVolume not setting due to looking at split[1] instead
of split[0]

* NOTE: TileMap2D now sets the positions of all of the tiles
* NOTE: When using keyboard input the key code is now in the format of
the codes in KeyboardInput
