Finalize new URL

[konklone]

Finishes the process #216 started, to update the site to point to the new URL.

• Updated _config.yml to change the site URL to be https://project-open-data.cio.gov
• Adds a rel=canonical link tag to point search engines et al to https://project-open-data.cio.gov/
• Any links that pointed to the old URL have now been changed to relative paths

A repo administrator still needs to update the URL visible at the top of the repo page to point to https://project-open-data.cio.gov/.

@philipashlock - game to confirm whether we should merge this?

[konklone]

I just updated my PR to deal with merge conflicts so that it's merge-ready. It looks like most of them are because my editor strips out trailing whitespace, which conflicted with others' future edits to those paragraphs.

[konklone]

I've updated my PR and fixed merge conflicts.

It may be easiest to review my PR by looking at it with whitespace stripping removed: https://github.com/project-open-data/project-open-data.github.io/pull/373/files?w=1

So..... funny story.

There are merge conflicts again. We're all currently within 30 feet of each other. Want to get in the same place and finally see this one out?

[konklone]

OK, I resolved the merge conflict. It required me to remove the line below this one, since license-examples has been removed. I also identified and fixed a merge conflict I failed to resolve last time.

How about a merge? 😺

[konklone]

Oh, and this is the best diff URL to review my changes:

https://github.com/project-open-data/project-open-data.github.io/pull/373/files?w=1

It omits changes that are only whitespace, leaving only the substantive changes in this PR.

Great - thanks a bunch and sorry for the hassle. I'm going to go ahead and merge.
