Title: Twitter's {source} doesn't work anymore

If you try to use the plugin as is for Twitter, you'll get this error:

Uncaught TypeError: Cannot call method 'replace' of undefined (line 179)

This is because list[item].source is undefined. Instead, I just pulled it out of the project as it didn't seem like a very useful feature anyway.
