    [cpp] added const qualifiers that had been removed (accidentaly\?) to LuminanceSourse pure virtual methods. Fixed build problem of ScanTest. Please check that ScanTest builds if you revert this, it will consist of removing const qualifyers to implementation these methods in sublass of LuminancesSource
