Invalid XML causes an uncatchable error to be thrown

[MadaraUchiha]

When trying to run generateWebfonts({ files: ['/path/to/invalid.xml'], e => console.log(e)), the application explodes with an uncatchable error like

events.js:136
      throw er; // Unhandled 'error' event
      ^

Error: Unexpected close tag

I'm guessing an error is thrown within a stream, and needs to be caught with the 'error' event in node.
