ADDED: -si and -sii to bb lint in order to show the interpreted and internally interpreted results of the rule parsing/lint operation.
IMPLEMENTED: WhereFrom.(MatchesConnected,  MatchesEnvelope, MatchesRouted)  and IPMask.Matches
BUGFIX: Due to previous change assigning default reject code/message to unspecified reject rules, tests were failing.  Made RejectCode and RejectMessage getters which return a set value or the default while letting the command output return match what the input was.
