Bring more epdfs for the tunes that I already have

From @veltzer's todo.

This seems to be in conflict with issue #37. Which would you like to do?

[veltzer]

Well, it is and it isn't. I'd like to see tunes carry information about where they are in other real/fake books. Somethink like this:

             attribute['location']='rbk1:56,57'

which means that the tune in in real book volume 1 pages 56, 57.

This is now done.
