Added console method detection

[cb1kenobi]

I know has.js already has native-console detection, but doesn't detect individual methods (log, warn, error, etc), so I added a couple test cases. Probably only useful for gathering metrics.

I think adding console method detection is a good idea. That being said, there are a couple things wrong with the detection methods.

1. Looping Performance - In general the for-in loop executes more slowly than the for loop. Since you're dealing with an array instead of an object, it would be more efficient to just use a for loop.
2. Method Type - Checking whether the console method type is a function will not work because in IE the type is an object.

The console in IE is actually an injected C object, not a native JavaScript object. You can test that by checking for the existence of JavaScript function methods, e.g. typeof console.log.apply, which will return undefined in IE.
