Title: Additional spy functions

As discussed in #45 I added ```callArg```, ```callArgWith```, ```yield``` and ```yieldTo``` to the spy API. They are applied to all calls.

To address a specific call, there are now additional convenience properties available: ```firstCall```, ```secondCall```, ```thirdCall``` and ```lastCall```.

Happy merging!
