    GfxDeviceNColorSpace: Port to std::vector<std::string>
    
    I was tired of having two constructors for GfxDeviceNColorSpace, both
    taking GooString ** but one copying those strings and the other keeping
    them for itself.
    
    Moved to std::vector<std::string> without much fallout in the rest of
    the code
