options: Add dummy -shuffle option to show it in -list-options
Add dummy -shuffle and -noshuffle options so they appear in
-list-options output. These features are not implemented as options;
rather they're features of the command line parser.
Also add the CONF_NOCFG flag to the existing playlist option, which is
a similar placeholder for a command line parser feature.
