$play will show tab completion from root drive directory if started with a /

[TahoeBennie]

Type "$play /" and watch the magic happen. If you are on windows, it will show all the contents of whatever drive it is playing off of. I've never used any other OS so i can't say anything about 'em. Similarly, typing "$play ../" will show the contents of the .minecraft folder it is using, and you can back it out even further too. Specifying a song to play like this works just fine.
