A lot has changed V2

1) The asyncore library finally is not what we need(old/async1.py).
Instead the select library is being used(async2.py).

2) changes are tested with myof_01_1.py instead of myof_01

3) Proxy is changing all the time in order to comply with the
underlying socket wrapper (async) and the layer above (of_01).

4) This version contains the basic functionality of simulating
that a switch is connecting but it works kind of randomly, though
correctly 90% of the times :-P
