* Base: When converting options to string, the returned value is a QStringList
        instance instead of a QString.

+ Core: The options, once returned correctly as QStringList, are being used to
        run the emulator correctly.

+ Core: Finally, the emulator can be run using a QProcess instance.

+ Base: Added option to configure the order of the options and the file. The new
        option specifies if the command is going to be built as "binary options
        file" or "binary file options". This change and addition is important
        since Mednafen has this difference when running on Windows and other
        systems.

+ Base: Added support for a string option, so, there is possible to configure
        string values.

+ Gui: Added support for the string option added to the configuration.
