rig.swg: New properly formatted macro

I made a patch, you can see in that there is the solution, which
describe the error: if a function in hamlib looks 3 argument
(rig, vfo, any 3rd arg), the order of the 2nd and 3rd argument
were reversed, because the macro METHOD1 reversed them.

I've collected these functions, compared its arguments with
hamlib docs (http://hamlib.sourceforge.net/manuals/1.2.15/), and
where 1st arg is rig, 2nd arg is vfo, and 3rd is any kind of
type, changed to METHOD3, which is a new macro, and keeps the
correct order of original function - see the patch. (I didn't
find any info about the expected diff format, so I just created
the `diff -uprN ORIG NEW'.)

To check my theory, I've tested with another function, which uses
vfo type at 2nd argument, eg. rig_set_freq; here is the Python
code:

  my_rig.set_freq(Hamlib.RIG_VFO_A, 7013200.0)

and the original code drop the exception:

    my_rig.set_freq(Hamlib.RIG_VFO_A, 7012500.0)
  File "/usr/local/lib/python2.7/dist-packages/Hamlib.py", line 2513, in
set_freq
    def set_freq(self, *args): return _Hamlib.Rig_set_freq(self, *args)
TypeError: in method 'Rig_set_freq', argument 3 of type 'vfo_t'

As you can see, it's same as my original error above.

So, after I patched the source and recompiled it again, these two
function works correctly - I will test it at soon, but I think
_this_ is good and stable.

Binding test scripts--fix set_freq ordering

Due to the changes of the patch contributed by Ervin Hegedüs, correct
the bindings test scripts to work with the corrected ordering of VFO and
frequency arguments.

Also add a call to send_morse() in each script.
