Auditlog-Export: Ziel/Details korrekt getrennt (v1.1.7)

Beim Export archivierter Auditlog-Tage (log_action("auditlog.export_delete", ...))
stand faelschlich die komplette Dateiliste im Feld "Ziel" (dadurch wurde die
Spalte in der Auditlog-Tabelle wieder unschoen breit), statt wie bei allen
anderen Aktionen ueblich einen kurzen Ressourcennamen im Ziel und die
ausfuehrliche Beschreibung in Details zu haben. Jetzt: Ziel = "Auditlog",
Details = Anzahl + exakte Dateinamen. Gleiche Korrektur fuer den
automatischen Archivierungslauf selbst (auditlog.archive). "Ziel"-Spalte
zusaetzlich mit white-space:nowrap gegen Umbrueche bei laengeren Werten
abgesichert.
