AJAM / HTTP + Manager In Trunk

Okay, so I've finally fleshed out my ideas more or less regarding manager and HTTP. I still think there is a great deal of optimization left to do in Manager to avoid duplication and directly writing to file descriptors from threads that are not the native thread of the entity using the manager interface, but that should follow later. I encourage anyone that's curious what all this is about to read doc/ajam.txt for more information about the new capabilities, and I welcome feedback :)
