Add QuickTime Media Link parsing. FIXME: Optional attributes (like fullscreen, volume, quitwhendone ...) are parsed but aren't used.

do not use vlc_t to store psz_pidfile

Someone should really review it as it is my first experience in C.

- also fixed a similar potential issue on subtitles.
- lesson for today: Be careful when you use p_parent of an object.

  - some elements are not yet supported.
  - it could perhaps use a little bit more cleaning.

In the basics. It just works :D
