This library is heavily inspired by J Cuga's golongpoll project. I just needed to simplify some things.

No more categories - each category needs to have its own longpoll instance.
Last Value Cache - when creating a new longpoll manager, you can specify if it should just cache the last published value rather than maintain a history of published values.
