Barrel-PR-1st-commit

Because a steel jerrycan of whiskey isn't classy enough for my liquor
cabinet. My 1st commit :)
Name change for barrel whiskey

Wanted to have a chance for this to spawn in liquor stores, but not sure
how to get around the already named whiskey
Commas names and liquor

Thank you for the review folks, updated changes/suggestions

to have the barrel spawn w/ just normal whiskey?
