Minor cosmetic changes

First, use %16p in debugging prints in offline context so that the
context address lines up with other uses of the address.

Second, add numbers to the AudioNode:NodeType enum. I'm tired of
counting every time I need to look up a node number when
DEBUG_AUDIONODE_REFERENCES is enabled.
