Prepare to publish panoptes.js

[srallen]

Package: lib-panoptes-js

This does three things:

• Reorganizes and updates the documentation. The docs are now readme files in the file structure itself which should make it easier to find I think and follows the pattern we've done elsewhere.
• Adds query param support to put and post in the least disruptive way I could think of (since put and post are being used in the UPP store) and specifically tests for the functionality to use the env query param to set the host across the board
• Removes the unused tutorial request helper for getting the attached media via an include. Deprecating the include param is requested in remove API include requests #678. We still need to deprecate project's helper getWithLinkedResources but this is being used in the project app, so it'll be best to do that on its own with a refactor in the project app and a major version bump when this happens.

I plan to do an initial published release of a minor version, 0.1.0

This looks good to me, but I'm still struggling to run the classifier at the moment. While I look into it again, I'm going to ask someone else to approve it.
