Issue #24: Füge PermissionEvaluator zur Gesamtprüfung der Berechtigung hinzu

Dieser PermissionEvaluator delegiert die einzelnen Prüfungen an PermissionEvaluatoren
welche `AbstractDelegatedPermissionEvaluator` erweitern.

Nur, wenn all diese PermissionEvaluatoren die Berechtigung erfolgreich geprüft haben,
gibt dieser PermissionEvaluator ein positives Prüfungsergebnis zurück.
