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.
The Sucroa flavor has been updated to the latest version. Alerts and the .nano progress bar have been removed, the .toast has been added using the color palette that the flavor uses, the alert colors have been moved to .card color variants, .drawer has been added using the colors of <nav>, generic shadows remain unchanged, based on the fact that the flavor still uses shadows, the .drawer component does not have a shadow by the way (I think it causes some problems, but this requires further testing). If anyone wants to update the flavor, please refer to this commit!
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.
Used a localized copy of the flavor file to style all the doc pages, added a few things wherever needed, added all download options, updated the README.
Fixed the display bug of .button-group on Chrome, should now display properly. Documented forms, inputs and checkboxes/radios, buttons, groups and mixins are coming.
