[ODE] more memory management pickyness

[Nate W]

As Russ said, these aren't really leaks, but still... I just can't stand
it when things show up in the 'memory leak' report. :-)  The previous
version of this didn't have the "if (classes)" check, so it would crash if
you hadn't actually created any geometry yet.  It also didn't free the
_data members of the classs and colliders arrays.


void dCloseODE () 
{
	if (classes)
	{
		for (int i = 0; i < classes->size (); i++)
		{
			dFree ((*classes)[i], sizeof (dxGeomClass));
		}
	}
	dFree (classes->_data, sizeof (dxGeomClass*) * classes->_anum);
	dFree (classes, sizeof(dArrayBase));
	
	dFree (colliders->_data, sizeof (dColliderEntry) * classes->_anum);
	dFree (colliders, sizeof(dArrayBase)); 
}

In order to get it to compile, I also had to make it a friend of class
dArray, like this:


extern "C" void dCloseODE (); 

template <class T> class dArray : public dArrayBase 
{
  friend void dCloseODE ();
public:
  etc, etc, etc...
