[A16] ThingFilter excludes qualityless items if normal quality is not allowed

[Thorbane]

The filter assigns anything with a stack size of one and no CompQuality a quality of normal.

If you set the stockpile filter to not allow normal quality items (ie. allow only good to legendary), things like AI cores, neurotrainers, artifacts and bodyparts will never be placed in that stockpile.

Working as intended, thanks for reporting though!
