mockuped new layout for wikipages when tinking about top contributors

** DO NOT MERGE **
this is just a test on how the wikipages could be arranged.
I was looking at #2127 and how the top contributors could be visually presented. It resulted in this mockup/POC. It can be viewed here https://developer-local.allizom.org/en-US/docs/Web/CSS/background-size and here are some thoughts:
1. IMHO The reading order is more relevant, "See also" is moved to a more natural place. eg. if you read from left to right you read, headline, content, TOC, and last complementary info and links.
2. I've tighten up the TOC and the complimentary column to be 250px instead of 315px, no need for them to take up so much space (And as a side note it fits like a glove in the [golden ratio](http://en.wikipedia.org/wiki/Golden_ratio)).

3. the line-lengths in the main column feels more comfortable like this. 
4. The last column enlightens the fact that this is a wiki

I know that other pages has been screwed up, I have only been focusing on a "normal" wikipage right now.

Thoughts?
