Default to json parser

[sethherr]

The standard lib json parser is good enough - and this definitely shouldn't be a required parameter.

And then, it swallows the error? Doesn't make sense to me. Frankly, to me, this entire bit should be removed and you should just parse with the standard lib if you get a string (ruby < 1.9 can figure it out themselves - particularly if there was an error thrown - oh wait, you require 1.9.3 so that doesn't even matter).

But in the interest of not making a major modification - it's already checking the type, why raise an error if it's a string? Why not just make life better and just work?

We should remove the json_parser option altogether & always use the stdlib. And add a test for the example that failed.

I mean, that makes sense to me - but that would be a breaking change. This doesn't break anything and seems like it could just be merged without a problem.

I could open a PR to remove the json_parser option after this if you'd like.

What do you think about #38 instead?

Looks good to me!

It will require a version update, but it's definitely a better answer. Closing this 🙂
