Relocate excess whitespace to edges instead of middle

The whitespace ocean that once parted the sidebar and the content has been displaced to the outside, surrounding a cozy 'container' of post and comment goodness. This 'ocean' is a darker shade of white so the page isn't so bright and one-color. Here are the screenshots:

The container is fully compatible with the mobile version.

The container is only applied to the main pages and not to pages with forms so that their widths do not conflict. Since this is experimental, I highly recommend first testing it locally. I've done some tests myself and found nothing of issue, but it should be tested on a second medium to make sure.

Let me know if you have any questions, concerns, or requests. In the case it's urgent, an email will get the fastest response, as always. :-)
