Updates from old website

[awwright]

Import all the updates from json-schema/json-schema#gh-pages since this group was created.

Before merging this, delete the gh-pages branch from https://github.com/json-schema/json-schema - @Julian can you take care of this step?

[Relequestual]

I'm not sure deleting the gh-pages repo is the right thing to do here.
I think we want all the changes made to the old orgs gh-pages branch... don't we?
Then, just update the contributing.md to redirect people to the new one (as well as removing the cname file)

[Relequestual]

Missed the fact that the PR was not from the json-schema org repo. Would say it's most likely fine to delete the old branch first. Thoughts @Julian ?

[Julian]

I should have permissions to do that, will have a look when I get to a computer

[Julian]

OK, done.

[Julian]

That appears to have 404'ed json-schema.org - I haven't been following very closely clearly -- are we waiting on a DNS change here?

[awwright]

@Julian Looks good from my end now, note it has the new website/project links

[awwright]

@Julian Now just merge in this PR and it should be good

[Relequestual]

Tag: Has conflicts... =/

[awwright]

When did this happen... sigh

[awwright]

Let's try this

Though I hope I didn't clobber any updates with the conflict resolution

[Relequestual]

I suggest waiting till I hear back from github support re the domain name fix

[Relequestual]

OK. As some of you know Github say the custom domain is now cleared. Who wants to push the merge button? =s

[awwright]

@Relequestual There's only three people who can do that

[Relequestual]

Done... Let's see what happens... =D

[Relequestual]

Looks like the update took! This means the domain is under "our control", as far as, it points to the correct github repo. Cool!
