This allows modules (and any other code) to implement arbitrary actions on server shutdown and "reload". Later will be used to address issues like #160. There are no plans to implement complete configuration reloading, however, since it adds a lot of problems to the modules framework and it is believed to be "not worth it" at the moment. Closes #130.
