Added missing image, and fixed link
Added coffee compiling, minifying, and concatenating
Non-cdn vendor files now compile to a minified `vendor.js` file.
Moved linkback js to coffee
Removed the linkback code from guidefooter.toffee
Moved share animations to animations.coffee
Moved search js into coffee.
Removed prettify

I believe *(hope?)* that prettify is legacy. I see no clear indiciation
of it's use, nor affect on the site. As of this point, i'm considering
it to be excess, and removing it.
Purged layout of sold very outdated code, and added videos coffee
Moved the search animation to the animations coffee file.

Also removed layout, since it was now empty.
Reworded comment.
