Support pushing multiple results to success handler

@dcsim0n I was making a few small changes to the example and realized the success handler isn't supporting multiple results - I took a pass at fixing that and wondered if you'd be willing to have a look at what I came up with?

[jessetane]

of course these changes would require a major version bump, which is fine by me

Coverage remained the same at 100.0% when pulling a772e5e on success-results into 691f70e on master.

another thought: we could instead drop support for multiple results and change the api so it's up to the user if they want to return an array?

[dcsim0n]

My first suggestion is something like this

callback(null,1,2,3,4) \passing multiple results

q.on('success', function(job, result1, result2){
//result1 === 1
//result2 === 2
//ignores other arguments that are passed
}
q.on('success',function(job,...results){
/// results === [1,2,3,4]

I understand this would break the current api by reversing the order that the job is passed, but it does make for an elegant implementation. The Rest operator syntax only exists for ES6 and up, not sure if that breaks anything for you.

good point, that is a little cleaner. will add a patch to try it when i get a chance, thanks.
