- What used to be the "Playlists" menu is now the context menu of the "Playlist Catalogue"
- Context menu includes an option to "Reset Playlist Catalogue Directory"

Also updated info regarding the "Create Playlist" option.

   three ways. Playing a file in a directory causes all the files in it
   to be placed in a playlist. Playlists can be created manually by
   either using the  \setting{Context Menu} (see \reference{ref:Contextmenu}) or using
   the \setting{Playlist} menu. Both automatically and manually created
   playlists can be edited using this menu.
