musicPathXML and musicPathSystem?

[shacker]

Library.py references these two objects, but it is unclear where they're supposed to be passed in from or what they do. Comments say:

        # musicPathXML and musicPathSystem will do path conversion
        # when xml is being processed on different OS then iTunes

iTunes is not an OS. I can't make any sense of this. If no one objects I'd like to delete these references.

It's possible they meant "when xml is being processed on a different OS than MacOS"? If the objects aren't being used anymore they can probably be removed. Could be a relic from when libpytunes did it's own XML parsing.

OK I'll wait until #52 lands and then remove this.
