activate commented Exception in Validator/Between::__construct

- [x]  if parameter is an array, it should have 'min' and 'max'.
- [x]  if the array parameter count !==2 and doesn't have 'min' or 'max' anymore, throws an Exception, because if array parameter count == 2, then 1st is a 'min', and 2nd is a 'max' like at 
```php
// at ZendTest\Validator\ValidatorChainTest::testIsValidWithParameters()
$this->assertTrue(StaticValidator::execute(5, 'Between', array(1, 10)));
```
