- added FfsBuilder code and UI, but reconstruction routines for volumes, files and sections are still not ready - FfsOps moved to common - QVector and QPair aren't used anymore, replaces with std::vector and std::pair - common classes are now independent from QObject - next step is to replace QString with CBString from bstrlib
