Fix GooglePlus parsing to return an integer without punctuation

The logic for parsing GooglePlus result inside sharrre.php return a number with punctuation when the count is greather than 1000. 

Before fix:
```
{"url":"http://www.ciandt.com","count":"3.169"}
```

After fix:
```
{"url":"http://www.ciandt.com","count":"3169"}
```

Then, when the js code parseInt() it, the results gets wrong, since, for example, 3.169 (more than 3 thousand) gets converted to integer 3.

```
        if(typeof json.count !== "undefined"){  //GooglePlus, Stumbleupon, Twitter, Pinterest and Digg
          var temp = json.count + '';
          temp = temp.replace('\u00c2\u00a0', '');  //remove google plus special chars
          count += parseInt(temp, 10);
        }
```
