Upgrade graphiql version to 0.17.5.

[DArtagan]

Updated the values on my machine and tested it out - things all seemed to be running fine.

Coverage remained the same at 93.548% when pulling cde885c on DArtagan:master into 0137ca1 on graphql-python:master.

@DArtagan to add, we now have a min.css as well. Note that difference in bundle size, too! we have an updated cdn example if you're interested.

I would also suggest using the latest react 16 sources, since react 15 hasn't seen a release or bugfix in over two years. with the new major version of GraphiQL in the works (alpha currently), we will switch to requiring 16.4 or later

This pull request should be aligned with #69 in order to provide offline support for graphiql. @jkimbo

will this be getting merged?

fyi, we should have a pretty plain 1.0.0 stable soon, just some bugfixes left. the alpha has some improvements already.

that said, 0.17.5, and the outstanding bugs are not major blockers, so 0.17.5 might be all you need for now.

here is a demo of our latest 1.0.0-alpha.8 via cdn:

this is the one that will require react 16.4 or greater.

2.0.0 RC is under development, and should have pretty good API parity.
