Fixed Spinner control bounds check error (#166)

The bounds check occurred before the `GuiButton`s for the increment and decrement feature of the `Spinner` control which meant using the buttons when the spinner value was at the `minValue` or `maxValue` and incremented or decremented past the min or max would not be resolved until the next time the `Spinner` control was called in the code, likely on the next iteration of a program loop. This caused an array index out of bounds issue in my codebase.
