Change specs to reduce load of Hatena Star

We check process of displaying stars and change system to reduce load average. At the new system if "☆123☆", this means this entry get 123 stars, is displayed. At the setout system does not read all information related stars information. It skips data of 123 icons. If user click "123" indication , star system gets actual information of numbers of star icons and display all information related with stars.

So far so good if user view an entry which has many stars, a load of browser get very high thus freeze can be occured. This problem was fixed.
