103 range operation

[skx]

Implement foreach support:

// Show the array
foreach item in [ "Steve", "Kemp" ] {
   print( "This is the element: ", item, "\n");
}

return false;

We don't get access to the index, but we do get the value. We could fix that later if we need it. This will fix #103 once merged - but note we have also changed the handling of OpCall, as per #86, and that needs to be fixed next.
