Patch by Torsten Spindler

Remark : should we keep the --telnet-port option that is now redundant ?

* Back to the hack for the isItem: inNode function, since this is several orders  faster than the high level functions provided by Cocoa... Playlist behaves corectly on big lists again...
* Fixes a bug in drag and drop

This (and previous patch) still needs some work as genres containing spaces
aren't parsed correctly

* vlc_symbols.h, vlc_playlist.h, view.c : add a function to remove a parent from the parent list of an item (if anybody wants to make that another way...)
* playlist.m: implements full drag and drop of playlist items. Drop of multiple items and of items and nodes at the same time should be supported. You cannot mode service discovery items. This is a choice and can be changed if wanted.
* Hopes that compiles on current trunk (cannot check since latest comits on net functions broke the built of a half the modules and core of the OSX port...)
