Comment 3 for bug 955346

It seems that there are two general issues here:
- the border of the empty stars are way too thick (if you for example look at the unicode characters ★★☆ it's directly clear which of the stars are filled and which ones aren't)
- we shouldn't display half stars - it's practically impossible to tell whether a star is a half star or a full star

(also i find that using three stars makes it so much easier to tell how many stars an application has than using five stars - ie looking at ★★☆ it's instantly clear that there are two stars, looking at ★★★★☆ it takes just that fraction longer to detect that there are four)
