This PR replaces the current CMS website with a static version of it built using Jekyll.
- Everything should be working 1 to 1 with the same permalinks except for the `/news` page (not articles) which was renamed as `/blog` (old links will redirect to new ones).
- The showcase entries on the home page now redirect to their showcase page in our site so that the user can choose which store front or page to visit next.
- I also changed the first link from the nav bar to go to the showcase page since the features one is still pretty outdated.
