Added tile_scale command that calls consoleScaleTiles(const char *string). This then converts the passed arguments of 'float x float y' (e.g., 'tile_scale 1.0 1.0' to scale to 1.0 times) to scaleTiles(float scale_x, float scale_y). If no argument is passed in the string, the default 2.0 scale is used. If the y property is not passed, the value of scale_x is used for scale_y.
