NPE if diffMaxViolations is not specified

[sjudd]

I believe that this is fixed by just defaulting diffMaxViolations to Integer.MAX_VALUE in ViolationsTask. A workaround is just to specify diffMaxViolationss when defining the task. I'll send a pull request shortly.

Out of curiosity, is there any particular reason to support Integer values for diffMaxViolations and maxViolations? Should those just be ints?
