Subject: [PATCH] iOS: Lagerort im Einzelstueck per QR scannen (ohne dessen
 eigenen QR)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Im Einzelstueck-Formular (bearbeiten und anlegen) gibt es jetzt neben dem
Lagerort-Dropdown einen "Lagerort scannen"-Knopf: den QR am Regal/Fach scannen
setzt den Ort direkt. So kann man z.B. Kleidung ohne eigenen Stueck-QR einem Ort
zuordnen. Neue wiederverwendbare LocationScannerView (…/l/<Code>).
