Cosmetics, and pull finding the playlist sorting function back to top level. The meta_* functions are still wildly inefficient, though.

A thank you to the Xbmc authors who had this fixed in their version of Martin Kahr's class.

When reading a file:// URL from an xspf entry, store the decoded file path; else store the unmodified URL

Always keep album art URLs always encoded and decode the path when needed
Interfaces & plugins only use file paths
Playlist core extract attachment:// URLs (from file meta data), http:// or other (from meta data fetchers like lua) and cache them to a file

Lots of strings still missing, help would be welcome
(cherry picked from commit 946eba4adf89f4727dcecf84e20cf8cf98110cb4)

Fix compilation
