Updated jsonpath to jsonpathv2.

[Skarlso]

Update reasons:

• To support scripting with JsonPath like $.store.book[?(@.price > 0)].title
• More up-to-date gem ( the other one has been abandoned for ~2 years now )
• Related issue: JSONPath parser is not parsing ?(@) conditions correctly #1591

Thanks @Skarlso!

One question: which license is https://github.com/joshbuddy/jsonpath under? We should make sure it's under a permissive license.

Edit: looks like MIT, so that's good. I wish it had an actual copy of the LICENSE, though.

[cantino]

I assume our ENV['ALLOW_JSONPATH_EVAL'] still works and defaults to false?

[Skarlso]

Hey, @cantino!
He is under MIT. So we should be fine.

Yes everything should still work. :-)

Looks good to me, great to see the code maintained again!

[Skarlso]

Thanks. :-) I hope I'll be able to do something awesome with it! :-)

[cantino]

@Skarlso You might want to add an actual MIT LICENSE file to the repository with his name on it (and your's?), but I'm comfortable since he had MIT in the gemspec. Thanks for doing this!

[Skarlso]

@cantino sure, I'll add that to make sure everything is by the books. Yw. I'll hope I can contribute more later on. :-)

Thanks! :)
