Error in Readability.js ?

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!

Start by inspecting Readability.js around lines 1219 and 1227, where elementProperty and content are handled before content.trim() is called. Reproduce the empty-content case and confirm that the chosen guard prevents the error without changing normal extraction behavior.
