    sidebar: Allow symbolic link as bookmark drop
    
    The gtk sidebar code currently only allows G_FILE_TYPE_DIRECTORY,
    G_FILE_TYPE_SHORTCUT, and G_FILE_TYPE_MOUNTABLE as acceptable drops
    to create a new bookmark.  Control+D successfully creates a bookmark
    for a sym link because it uses nautilus code.  Since sym links are
    acceptable bookmarks, allow G_FILE_TYPE_SYMBOLIC_LINK as an allowed
    drop for bookmarks.
