Drop -S stack option

The -P option already stacks. The -S option was only used for changing the
stacking order. Simply require the correct order with -P. This reduces
the confusion in stacking.

-This option allows the user to specify a protocol decoder stack, i.e.
-the way in which one protocol decoder's output gets piped into another
-protocol decoder. If not specified, the stack will be set up in the same
-order in which the protocol decoders were given with the
-.B \-\-protocol-decoders
-option.

-The decoders are specified by their ID, as shown in the
-.B \-\-version

-.B \-S

-(together with their options, if any) using the
-.B \-P
