The IECoreRI.Renderer class uses 3delight's new instance scoping mechanism to
place all instances created with instanceBegin() at the world scope. This allows procedurals to create instances to be used in other procedurals.

Removed deprecated "objectBegin", "objectEnd" and objectInstance" commands from IECoreRI.Renderer. Use the instanceBegin(), instanceEnd() and instance() methods instead.

Minor change to prevent recursion in WrapperGarbageCollector::collect(), which was leading to python objects with negative reference counts in the situation where a destructor created an object inheriting from WrapperGarbageColloctor

Removed Py_DECREF() from Wrapper destructor. The only way this destructor gets invoked is via another Py_DECREF() in WrapperGarbageCollector::collect(), so m_pyObject usually has a zero reference count anyway. Occasionally though, python creates a new python object with exactly the same address as the one that's just been destroyed, before invoking the destructor code. This means Py_DECREF() gets called on an object that's just been created, leading to dangling pointers and crashes.

It turns out that WrapperGarbageCollector::collect() can sometimes get called recursively through Py_DECREF(), which was occasionally leading to double deallocations. The code has now been rearranged slightly to avoid these double deallocations.
