Error in Readability.js ?

[fernand0]

I'm using readabilitpy 0.2.0 and I've found what I think is an error. In file Readability.js, in line 1227, there is the line:

             values[name] = content.trim();

But content can be empty and it will produce an error. I've solved it in line 1219, adding a check for content:

       if (elementProperty && content) {

But I'm not sure if it is the correct way to deal with the issue. I can send a PR if this is ok.

Best regards, thank you and keep up the good work!
