Subject: [PATCH] Fix a bug when sorting the playlist:

Actually sort is well done but when the user ask for the next/previous item in
the playlist, it will get the one without the sort and not the right
previous/next item.

This is caused by the fact that the table which describe previous/next isn't
rebuilded after a call to the sort function. This commit force the rebuild to
be done (b_reset_currently_playing = true)
