Context document

[AndersDJohnson]

Contexts now dereference on the root of the document to which they belong, rather than on their own (sub-)node or any parent context(s).

I believe this behavior was the intent of the changes by @slavaschmidt for parent context dereferencing in #15. @slavaschmidt, can you see if this branch passes your use cases?

P.S. This behavior may have to change if we ever implement relative pointers per #19.

Still pending tests with self-references in referenced external documents.

@adjohnson916 Thanks for fixing that. These are exactly the changes I was mentioning. I can't test all of the use cases but I'll check at least these I have and report the results. Sorry, this will take a day or two because of the current state of the play-swagger branch I'm integrating with.

@slavaschmidt Thanks, keep me updated if you can.
