qt seed completer: colour words yellow if only in old electrum list
Some people complained that due to merging the two word lists,
it is difficult to restore from a metal backup, as they planned
tto rely on the "4 letter prefixes are unique in bip39 word list" property.
So we colour words that are only in old list.
