This brings over the memory leak fixes for pointers to structs with a %extend destructor from my Neha fork.  The generator was not generating and connecting the needed code for the requested destructor to the v8 dtor finalizer.

I did not realize this branch has some JavaScriptCore stuff in it too. Unfortunately, it seems to have its own unique problems (like creating C++ files when it should be generating C files). My changes are targeted for v8, and I don't think my JSCore changes fully reach in this JSCore implementation so more work would need to be done to get this branch working. I think my Neha fork is in better shape at the moment.

Also, I did port over the 'NULL out the dtor function pointer' in the %nodefaultdtor fix to v8.

Usage case:
struct MyData {
%extend {
~MyData() {
FreeData($self);
}
}
};
%newobject CreateData;
struct MyData* CreateData(void);
%delobject FreeData;
void FreeData(struct MyData* the_data);

where the use case is something like:
var my_data = example.CreateData();
my_data = null;
v8: Removed the extern "C" around the initialize function because it makes no sense since it requires a C++ templates object as a parameter.
v8: variable name bug fix in my template modifications for pointers to structs.
