Calls to checks for a speific check return undefined

[rwky]

If you run checks with the target option then the callback receives undefined because Pingdom's API returns 'check' instead of 'checks'.

The property variable needs to be set to 'check' for this kind of check.

api.checks(function(err,check) { 
    console.log(check); //outputs undefined
},{target:111111});

Valid point. I'll accept a PR for this gladly. If you aren't in a hurry I'll eventually fix this on my own, though. :)

I'll create a PR next week, after I've played with the API a bit more.

Ok, great!
