SDL Word Cloud: Please update to ignore reference files in project

Hi,

I emailed sdk-feedback@sdl.com a while back, but haven't got any response and the word cloud plugin on OpenExchange is still at version 1.0.

Basically, I'd like the word cloud plugin to be able to work with projects that have reference files:

Basically the error message says "Unable to cast object of type ReferenceFile to type ITranslatableFile"
