Gilded & Masturbation Tweaking

* Got bold and named the next release and added my name to the credits
screen along with a little polish...
* New Function: `Utils.randomNumber(low, high)` - returns an int between
`low` and `high`
* Then used it to give multi-cocked herms a random "continued scene"
with the Onaholes.
* Tweaked Gilded gem reward downwards at the milker
* Cleaned code for All-Natural Onahole--its output was identical except
for a few words for multi- and single cocked players
