* implement set videomode via json api * refactor grabbers: - new base class - move shared code to base class * fix osx * rework all cmakelist files with auto file collection. except leddevices (need further restructuring) * store current video and grabbing mode * add json stuff * remove grabbingmode - we do not want to expose it
