DJ Jocky - CCU2 Feature

--[[
DJ Jocky
Made by: willwac (NewCoolPC) & Zambonie (PAT457)
This is a simple DJ program that doesn't use turtles
At CCU2, turtles cannot be accessed by students,
 but we wanted a DJ system, so we made this!

To use:
1: Place down 12 disk drives, and network them to
 the computer.
2: Edit the table below to match the drive numbers.
3: Edit the top bar text if you wish.
4: Save, and run DJ Jocky, make sure it works.
5: Rename DJ Jocky to "startup".
6: +1, comment, and suscribe to the forum thread
 if you wish.
7: Talk about CCU2 if you wish.
8: Give us feedback, and please, please report bugs
9: After you've done the above, listen to some
 great tunes!
