event.get_keyword() is very useful, since extensions may use multiple keywords, and in this case there's a need to distinguish between them in KeywordQueryEventListener.

However, it gets the user defined keyword, not the keyword id. Since users can change these it has to be converted back to the keyword id.

This is not hard by any means, but it feels like a hack having to do it.
