GitHub Enterprise features page redesign

Updates to the GitHub Enterprise features page design, layout, and content. The new page has an improved focus on showcasing why you should buy Enterprise.

There is a handy comparison table based on the fine work of @James Kang's PDF for the sales team, new illustrations, and a metric shit-ton of copy improvements via @stephbwills and other helpful voices.
