Beanstalkd: add FSM diagram for connections

[ysmolsky]

Not sure that it has much of use really. Just created while was exploring sources.

Should we add it to sources as an ASCII diagram?

How about as a dot file? This input file generates this image:

@pseudocodes , nice job! Can you compress it a little so it will take less columns and rows?
