Allow false values

It seems to me that it would be very useful to allow both boolean values for all boolean rules. E.g., disallowMultipleLineBreaks can be set to true but not false.

AssertionError: disallowMultipleLineBreaks option requires true value or should be removed

It's nice to be able to set rules like this to either value when trying out the features, and so other devs can see what rules are available without having to look up the node-jscs docs. It wouldn't be so bad if JSON allowed use to comment-out lines.

Nevermind this.. I can see the reason for not allowing more than one value per rule.
