Lagerorte: ueberall ein aufklappbarer Baum statt flacher Pfadliste

Die Lagerort-Auswahl schrieb in jeder Zeile den ganzen Pfad aus
("Hedingen → Guido Zimmer → Kallax → Fach Oben Links → Oben"). Bei einem
tiefen Baum ist das eine Wand aus Wiederholungen, und Geschwister stehen
nur zufaellig beieinander.

Jetzt dasselbe Auswahlfeld wie bei den Kategorien: eingerueckter Baum,
Aeste ein- und ausklappbar. Geschlossen steht weiter der volle Pfad da -
"Oben" allein waere nicht eindeutig, genau dafuer war der Pfad gedacht.

CategorySelect konnte das schon und war auf Lagerort-Codes vorbereitet
(seine IDs duerfen Zeichenketten sein). Dazu kam nur LocationSelect als
duenne Huelle: Baumaufbau und die Umrechnung "" <-> null, damit die 16
Aufrufstellen weiter mit dem leeren String fuer "kein Ort" arbeiten.

Zwei Kleinigkeiten dabei: CategorySelect bekommt showRoot, weil bei den
Mindestbestaenden "nichts gewaehlt" kein gueltiger Wert ist - dort heisst
die oberste Zeile "Ueberall". Und LocationSelect sortiert Geschwister
selbst nach Namen; der Server sortiert zeichenweise, dort stuende "Fach
oben Rechts" hinter "Fach Unten Rechts".
