storedPlaylist: cleanup load function 

* stop supporting unused parentlen block, I have no idea how it
was ever usable, but playlists don't work in subdirectories...

* myFgets is far easier to use than fgetc loops.

* Since we're using myFgets, we'll just skip lines that are too
long, rather than error out and bitch and moan about things...
