Initialer Commit: Kundenverwaltung (PHP/Smarty)

Bestehende Codebasis als Ausgangsstand aufgenommen.

- .gitignore: Kundendaten (uploads_*), Smarty-Compile-Cache
  (templates_c), Laufzeit-Temp und Datenbank-Dumps ausgeschlossen;
  Verzeichnisstruktur ueber .gitkeep erhalten
- .gitattributes: Zeilenenden normalisiert (LF im Repo),
  Binaerformate markiert
- db-backup.php: MySQL-Zugangsdaten kommen jetzt wie im Rest der
  Anwendung aus der externen Konfiguration statt hartkodiert aus der
  Datei; Passwort wird ueber eine temporaere Optionsdatei statt per
  Kommandozeile uebergeben, Fehler von mysqldump/gzip werden gemeldet,
  Aufraeumen aelterer Backups berechnet Jahr und Monat konsistent
