Pretty sizeable documentation update, improving layout, typos etc. Also added the Codepen Project to the templates page, a small note to star the project in the front page and two more examples in the drawer component documentation to make sure that everything is properly documented.
All docs (except customization which will be updated in the next commit) have been updated to use the new drawer on mobile and have had their version tags updated. New menu items and links are now properly shown in the menus.
