Merge pull request #95 from swipely/fix-image-tag-again

Fix image tag again
Update the dockly reference in the README.
Now creating the image id in the form repo:tag
Version bump 1.8.3
Merge pull request #96 from swipely/fix-image-create-with-tag

Fix image create with tag
Docker::Image.create now sets the id correctly.

I'm a bit surpised that this has not been an issue thus far.
Now extracting the ID as if the response was JSON

This took a bit of regex magic, but hopefully they'll fix the remote api
to ACTUALLY return JSON.
Re-record broken/verbose VCRs.
Version bump 1.8.4
Merge pull request #97 from swipely/add-correct-id-to-image-create

Docker::Image.create now sets the id correctly.
Add Docker::Util.fix_json.

The "JSON" that is returned by the API isn't parsable. This is because
it's not actually JSON, since there are no delimiters between each hash.
Docker::Util.fix_json attempts to rectify that.
All specs passing with remote api version 1.9.
Add the X-Registry-Config header.

Although this header is only needed for posting to `/build', sending it
with every auth request doesn't hurt and simplifies the code.
