Improved website header and more

- Hello everyone, this is going to be the last celebration update for the website and as it is less than 2 days to finish Purple Update, we decided to change the website header to be more suitable for higher resolution displays (1920x1080 or higher) and We changed the menu to follow this process.

We just changed our mind about the new service we recently introduced and now it works like a user help page. We will improve this page over time, you can always contribute your feedback.
