Update LICENSE
OK, I got a little bit carried away with this commit. Basically, I
removed the necessity of specifying what element we want to scroll on,
and instead am just listening to the window's onscroll method.

ADDITIONALLY, I added the ability to play multiple fart sounds at a
time, as mentioned in #17 and #22. Otherwise, the farts sounded a bit
choppy.
Prevent multiple audio players, as pointed out in #29
Note the jQuery removal
One day, I'll figure out markdown
Moving global audio variables. Closes #28.
farting in a more functional way
I don't want to "overly prefix" mp3's
spaces
Use window.addEventListener, so as to not mess with any other window.onscroll handlers. (Closes #40)
Merge pull request #8 from runn1ng/master

This is important.
Adding version
Merge branch 'master' of github.com:theonion/fartscroll.js
Mentioning the CDN
verify the audio is different each play

if the same audio item is played consecutively, it breaks the illusion we are trying to create
