I added a keyword "property" to the old tolua 3.2 version that was pretty
useful.  It worked something like this...

C++ class:

class MyClass {

    // Read write property
    int GetValue();
    int SetValue();

   // Readonly property
   int GetValue2();
};

tolua PKG class:

class MyClass {

  property int Value;
  property const int Value2;

};

Then in lua, the Get/Set function pair becomes a propery value which looks
just like a table var.

myinst.Value = 100
i = myinst.Value
i = minst.Value2

I've also noticed that 'tolua' adds a whole lot of string constants
reporting errors, so I took those out.
