KeywordSet.addKeywordRef() does not check for duplicates

[ogerboss]

KeywordSet.addKeywordRef() does not check if the keyword you want to add is already present in the KeywordSet. If it's present, it will simply be added a second time.

Could you alter this function to just do nothing if the new Keyword is already present?
