Fix FileManagement Build-Fehler (BUILD_RTI=OFF)

- flm_db.h: Stub-Header mit Folder/FileContent Klassen erstellt
- flm_enums.hpp: MainFolder Enum hinzugefügt (None=0)
- flm_translation.h: toInt() entfernt, trFolderName() angepasst
- Plugin-Interfaces erstellt (flm, opm, exm)
- Viewer-Dialogs: QString-Konvertierungen behoben
- AdvancedSymbology CMakeLists.txt: Ungültige Pfade entfernt
- ism_mounting_point.cpp: Redundante Definitionen entfernt
