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.
Changed the splash logo and updated a lot of the branding for the framework. A follow-up commit will be made to resolve a minor issuue with the documentation images.
Created a new folder, 'customization', under which the new Customization documentation will be added (replaces wiki). All the old page navigation links have been updated to point to it, while the old 'customization.html' page now redirects to the new one.
