* Device.css3D has been removed, and the function that tested it is no longer run.
* Device.isConsoleOpen has been removed. The function only worked on a very limited set of old browsers.
* Device.littleEndian has been removed, you can use Device.LITTLE_ENDIAN instead.
* Phaser.ArrayUtils.numberArray now has optional `prefix` and `suffix` arguments, allowing you to do: `numberArray(1, 4, 'Level ')` and the Array will contain `["Level 1", "Level 2", "Level 3", "Level 4"]`.

* Create an array representing the inclusive range of numbers (usually integers) in `[start, end]`.
* Create an array representing the range of numbers (usually integers), between, and inclusive of,
* the given `start` and `end` arguments. For example:
*
* `var array = numberArray(2, 4); // array = [2, 3, 4]`
* `var array = numberArray(0, 9); // array = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]`
*
* This is equivalent to `numberArrayStep(start, end, 1)`.
*
* You can optionally provide a prefix and / or suffix string. If given the array will contain
* strings, not integers. For example:
*
* `var array = numberArray(1, 4, 'Level '); // array = ["Level 1", "Level 2", "Level 3", "Level 4"]`
* `var array = numberArray(5, 7, 'HD-', '.png'); // array = ["HD-5.png", "HD-6.png", "HD-7.png"]`
*
* @method Phaser.ArrayUtils#numberArray
* @param {number} start - The minimum value the array starts with.
* @param {number} end - The maximum value the array contains.
* @return {number[]} The array of number values.
* @param {string} [prefix] - Optional prefix to place before the number. If provided the array will contain strings, not integers.
* @param {string} [suffix] - Optional suffix to place after the number. If provided the array will contain strings, not integers.
* @return {number[]|string[]} The array of number values, or strings if a prefix or suffix was provided.
