fix setup.py to use the git version of spool
version++
Version 0.2 :
 - Remove spool from requirements, write own "async lib" and pipes.
 - Messages are now going through Pipes, no more strings.
 - Events propagate themselves to each listener
 - The first client (MasterClient) has now a unique status and waits/blocks until connection is ready to send messages to the socket
 - File (re-)organization and transform mainloop in an object
