[boost] [intrusive] slist error and hashtable_node problem

Hello, I think I found two more issues with intrusive: 1. boost/intrusive/slist.hpp:908 This line calls the non-existing method insert_after_and_dispose(). 2. boost/intrusive/detail/hashtable_node.hpp:65 The operator=() of bucket_impl is missing a return statement. Regards, Markus
