IntegerAnswerFormat validation with no max value.

According to the comment on the constructor and on getMaxValue 0 should be used to specify no max value but the validation never checks for a zero value.

@param maxValue maximum allowed value, 0 if no max

Validation:

...
else if(intAnswer > getMaxValue())
{
    return new BodyAnswer(false,
    R.string.rsb_invalid_answer_integer_over,
    String.valueOf(getMaxValue()));
}

It looks like the corresponding ResearchKit class uses ‘nil’ for unused min/max values. I think that settles it in favor of null, or the same survey JSON will yield different outcomes for the two platforms.

Maybe I’ll keep the return type to getMaxValue()/ getMinValue() as ints and return MAX_INT/MIN_INT there to avoid breaking any custom validators.
