This PR merges the NodeConnCB and SingleNodeConnCB into a single class (called NodeConnCB). The original intent for the NodeConnCB was to be able to have a python 'mininode' connect to multiple running bitcoinds. This has never been used and can be achieved more easily by having multiple NodeConns backed by a common datastore if it is ever needed.

The changes in mininode.py are just code moves (and merging the two classes into a single class). The code changes in the individual test cases are changing the subclasses to subclass from NodeConnCB instead of SingleNodeConnCB. There is a lot of duplicate code in the subclasses that can be removed in future commits. @sdaftuar as discussed - should be an easy review.

style nit: Any reason you don't mention on_pong here?

I put all the no-op callbacks in this block and the callbacks that do something below. Happy to move them around if you think that's unclear.
