better project tree structure for obfs-flash/fog
The project tree structure is quite disorganised atm. Now is probably a good time to turn it into modules, before we write too much more code.
See obfsproxy and pyptlib for an example of how to structure a python project. See websocket and goptlib for an example of how to structure a go project.
