Unknown options are ignored instead of throwing UnrecognizedOptionException

CLI does not handle unknown options, i.e. throw an 'UnrecognizedOptionException'.
The reason is that the logic of PosixParser.processOptionToken() is incomplete:

if (this.options.hasOption(token))

{ currentOption = this.options.getOption(token); tokens.add(token); }

else if (stopAtNonOption)

{ eatTheRest = true; }

ie. if the stopAtNonOption is not set and the token is unknown, it
will be ignored. there has to be a default case added:

else

{ tokens.add(token); }

in which case the caller will throw the proper exception, because
in Parse there is another check whether the option exists.

i would've submitted a patch but did not find where to, sorry.
