Title: Add ability to randomize filenames

I usually like my filenames randomized, so I added it. Feel free to close if you don't want this functionality. :star2:

On a side note, normally I wouldn't be comfortable with hard-coding an alphabet, but in this case it'd be a bit wasteful to try to convert from a `NSCharacterSet` just to get an array of characters for permutations.
