Product pages (/features) redesign

Working on an idea for the product pages - not looking to deploy for the time being as there's still some discussion about where this will live (ie, /features or /features/dashboard) and how certain minor aspects of the page might be affected by this decision, but it's ready for some code review and for people to have a peek!
