Use core default value for viewport width

[richtabor]

Fixes #683 by adjusting the previous 800 value for the default viewport width to 1200, which matches the default value in core. This way patterns render the same, regardless of source.

@richtabor Thanks for the PR! I've deployed this, but it only affects the default value. Most patterns by wordpressdotorg have this value set already, and most of those use 800. There are some at 1200, 1000, and one at 600. If you want any of these updated let me know, I can do it from my sandbox.
