added functionality - it.only, jshint, console.log

@rgarcia not so fast! I agree with your general philosophy towards linting - that lint failures should be fixed, not ignored. But historical precedent has shown that if lint becomes even the tiniest bit untrustworthy (e.g. shows you a warning you don't care about), people will start ignoring it.

Maybe we need to do as Chris suggested and invest a bit of time in cleaning up our codebase so that lint output can be more useful.
