- Add an explicit constructor SGSoundSample(const SGPath& file) that directly uses the specified path instead of going through ResourceManager::findPath(). - Reimplement the existing constructor as SGSoundSample(const std::string& file, const SGPath& dir), delegating to the new one. - The first argument of the delegating constructor is now a const std::string& instead of a const char*. Among others, this will allow a better implementation of FGSoundManager::playAudioSampleCommand(). More explanations can be found here: https://sourceforge.net/p/flightgear/mailman/message/37695786/
