Title: Added eitherDecode and eitherDecode'

Hi Bryan,

When debugging REST API's that accept and return JSON it's really helpful to receive error messages why JSON decoding failed. The attached patch adds `eitherDecode` and `eitherDecode'` which are just like `decode` and `decode'` respectively but return an error message when decoding fails.

I'm not sure about the names yet but I couldn't think of something better.
