Update of service

Today,

I change the interface of the service and create a new logo.

I also optimize database. I have accelerated the service by creating a new table that contain neighbors count. Before this change, some query took longer than 5 minutes to return result. Now it's faster than ever. Give a try on domain parked on GoDaddy server like "bizarrechef.com", "blu-pr.com" or "bonneterrepaintball.com" these query return more than 4 millions neighbors.
