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

Fix mozilla autoconf check : AC_PATH_PROGS() was used incorrectly, and the check wouldn't error if {mozilla,seamonkey}-config or xulrunner wasn't found

Lots of strings still missing, help would be welcome

playlist sorting: for inline to work, the text has to be available. IE putting the function behind all others that use it isn't going to work, and marking forward declarations inline won't help fix it.

No need to backport this, as 1.0-bugfix only includes classic nibs

"daemon" is kept as the default, other accepted values are for now
"user" and "local0" through "local7"

Seperate config options from the configtree. VLCTreeItem and VLCTreeLeafItem
are now used for CONFIG_ITEM in an options collection. It now works, but
probably should be cleanup up a bit more, with better seperation between the
disjunct elements of Tree and ConfigItems.

This was broken since [09e31e1436ef3e670bd7497688272dd073c8d3a6]
