quality must be set from deliveries

Circuit network signals can only have exact qualities and can only set exact filters on inserters.
Ultimately this means Cybersyn must handle each quality separately.
For now the quality is hardcoded to comparator "=", quality "normal".
Cybercyn's output constant combinators won't send signals otherwise.
