If a vulnerability is found wpscan should exit with return code of 1

[tas50]

This allows easily wrapping it within scripts that just check for the return code. It would be particularly useful to have wpscan run as a jenkins job. Right now when it finds something jenkins sees a success since the return code is still 0.
