Add persistent log file and "Protokoll" viewer button

Tray-Meldungen verschwinden - daher ein dauerhaftes Protokoll. - Logger: threadsicheres Datei-Log in %AppData%\StarfaceOutlookSync\sync.log mit Rotation bei 2 MB. - MainForm protokolliert Sync-Start, Ergebnis, Konflikte (lokal + von anderen Arbeitsplaetzen), Fehler und uebersprungene Laeufe (Sperre). - Neuer Button "Protokoll" oeffnet LogViewerForm (Aktualisieren/Leeren/Ordner oeffnen, scrollt ans Ende). - README/CHANGELOG aktualisiert.
