Enhance AgentKey with comment, inner_key attributes

- Comment was being read-but-not-stored from the agent reply. wat?
- Use newly added PKey constructor to instantiate a key subclass for the
  'inner'/proxied key, this way client code can obtain stuff like bit
  size, fingerprint, etc.
- Proxy to inner_key with __getattr__ so clients don't have to know
  whether they're dealing with an AgentKey or a regular one
- Add `__repr__` to PKey instead of doing it in AgentKey. (wow, how did
  we not have this ever?)
