* Really handy function for when you are creating arrays of animation data but it's using frame names and not numbers.
* For example imagine you've got 30 frames named: 'explosion_0001-large' to 'explosion_0030-large'
* You could use this function to generate those by doing: Phaser.Animation.generateFrameNames('explosion_', 1, 30, '-large', 4);
*
* @method Phaser.Animation.generateFrameNames
* @static
* @param {string} prefix - The start of the filename. If the filename was 'explosion_0001-large' the prefix would be 'explosion_'.
* @param {number} start - The number to start sequentially counting from. If your frames are named 'explosion_0001' to 'explosion_0034' the start is 1.
* @param {number} stop - The number to count to. If your frames are named 'explosion_0001' to 'explosion_0034' the stop value is 34.
* @param {string} [suffix=''] - The end of the filename. If the filename was 'explosion_0001-large' the prefix would be '-large'.
* @param {number} [zeroPad=0] - The number of zeros to pad the min and max values with. If your frames are named 'explosion_0001' to 'explosion_0034' then the zeroPad is 4.
* @return {string[]} An array of framenames.
