Accept empty :english (might make sense for custom names)
combine-duplicates already at ConvertCCDict.clj

ConvertCCDict.clj to use clojure-clr and Utils

Show window quickly upon startup, before Clojure runtime start
When setting some property of a word not yet in words.clj, copy all props from large dictionary to ensure full independent usage
