Subject: Engine: Reduced thread pollution

Because of the frequent Sequencer reinitalization, many shutdown hook threads designed to close the Sequencer upon exit were created, which polluted the environment with many unneeded thread.  To solve this, the shutdown hook is now only created the first time the Sequencer is initalized.
