Add cross-client sync lock via shared directory

Browse Source 
Verhindert, dass mehrere Arbeitsplaetze gleichzeitig dasselbe Starface-
Adressbuch synchronisieren (Dubletten/Lost-Updates bei echter Ueberlappung).

- Neues optionales Setting "Gemeinsames Verzeichnis" (UserSettings.SharedDirectory)
  in der Einstellungen-Maske inkl. Ordner-Browser.
- SyncLock: atomare Lock-Datei (FileMode.CreateNew) im gemeinsamen Verzeichnis,
  waehrend des Syncs offen gehalten -> bei Absturz gibt das OS das Handle frei
  und ein anderer Client uebernimmt die verwaiste Datei (Stale-Erkennung 15 Min,
  Loeschen scheitert am offenen Handle eines lebenden Halters).
- MainForm wartet vor dem Sync bis zu 2 Min auf eine freie Sperre, sonst wird
  der Lauf uebersprungen. Ohne/bei nicht erreichbarem Verzeichnis laeuft der
  Sync ohne diese Sperre weiter (lokaler Interlocked-Schutz bleibt).
