#114 Cannot modify playlists

[Marcus Sundman]

I open a playlist (which is in my music directory, not in ~/.zinf),
modify it (e.g. remove an entry) and then press the Save (NOT
"Save As...") button. The stupid thing now asks for a name, and
even though I give it the same name as it already has it will be saved
as a completely new playlist (in ~/.zinf). Apparently there is no way
to modify an existing playlist.

Also, the "Save This List to Disk?" dialog opens _under_ the music
library window, which completely obscures it. (Also, are you from
Germany or what's up with having almost all words begin with
upper case letters?)
