Graphics/InstancedRenderable: Add Clone method

ChangeLog.md

@@ -109,6 +109,8 @@ Nazara Engine:
 - Fixed SocketPoller not be able to recover from some errors (like invalid sockets and such)
 - ⚠️ Replaced currentBitPos and currentByte fields by [read|write][BitPos][Byte] to handle properly bit reading/writing. 
 - InstancedRenderable::SetMaterial methods are now public.
+- Fixed Model copy constructor not copying materials
+- ⚠️ Added InstancedRenderable::Clone() method
 
 Nazara Development Kit:
 - Added ImageWidget (#139)
