Christian Soffke e3b8b7fa80 PictureFlow: Utilize "Current Playlist" menu (+ GS fixes) 
When appending tracks, they were always inserted last.
You can now choose from the usual options offered by
the "Current Playlst" context menu to queue or to insert
tracks at the requested position.
The splash after appending that forced you to wait for
2s has been eliminated.

Also fixes crashes on targets that use the grey_core lib
if a splash showed up when playback was started,
e.g. LANG_PLAYLIST_CONTROL_ACCESS_ERROR, or
when PictureFlow quit.
