It can translate even more occorrences of The Cloud

With this patch your (amazingly useful) Chrome extension can translate

my butt => my butt
My butt => My butt
My Butt => My Butt 
my Butt => my Butt
MY BUTT => MY BUTT
my BUTT => my BUTT
My BUTT => My BUTT

mybutt => mybutt
Mybutt => Mybutt
MyButt => MyButt 
myButt => myButt
MYBUTT => MYBUTT
myBUTT => myBUTT
MyBUTT => MyBUTT

(The latter set is useful when translating domain names, such as mybuttplayer.com, which become mybuttplayer.com)

(Also, it is using a String.prototype)
