FGNasalSys vs FGPythonSys - common baseclass

These are APIs that are sufficiently generic in nature to be moved to a common baseclass that can be shared by FGPythonSys/FGNasalSys:

• fgvalidatePath()
• loadResoureFile (fgdata access)
• printlog(), i.e. wrapping SG_LOG() [1]
• loadModule()
• loadPropertyScripts()
• addcommand()/removecomand()
• runfgcommand() (with locking, e.g. using SGMutex)

class FGScriptingSystem : public SGSubsystem, public SGPropertyChangeListener {
public:
    FGScriptingSystem();
    virtual ~FGScriptingSystem();

   const char* readfile(const char* file, int* lenOut);

    // Subsystem functions.
    virtual void init();
    virtual void reinit();
    virtual void bind();
    virtual void unbind();
    virtual void update(double dt);
protected:
    // Load and execute a script.
    bool loadModule(SGPath file, const char *module) = 0;
    virtual void loadPropertyScripts() = 0;
    virtual void loadPropertyScripts(SGPropertyNode *n) = 0;
