Fixing zeroOrMore() and oneOrMore() methods

[Tavio]

This is a fix for issue https://github.com/VerbalExpressions/JavaVerbalExpressions/issues/36.

zeroOrMore() and oneOrMore() methods now accept a parameter just like the maybe method() in order to generate correct expressions.

As a temporary side effect, it is no longer possible to do things like regex().digit().zeroOrMore(). I intend to fix this in a future PR.

I think implementing of current behaviour can be done in this pr
