EZ Keyboard v0.02

Added new library of mp3's now including two octaves of every note,
reset all the id's to more revenant names, updated the whatKey function
to include 9 notes allowing for major's and relative minors, updated
all instances where # was used to indicate a sharp note and used x in
place of #(because the # symbol kept breaking the code), created a
sound div so all sound were assigned to the same div, this prevented
them from ringing out if another key was engaged
