jpegquality should not be stored in protocol.py!

[Antoine Martin]

Why is it there?
It has nothing to do with the network layer...

I only noticed it because during testing something went wrong and the current connection got dropped, then I got this enlightening stacktrace:

Unhandled error while processing packet from peer
Traceback (most recent call last):
  File "xpra/protocol.py", line 457, in _process_packet
    self._process_packet_cb(self, decoded)
  File "xpra/server.py", line 2072, in process_packet
    handler(self, proto, packet)
  File "xpra/server.py", line 1519, in _process_hello
    self._protocol.jpegquality = capabilities["jpeg"]
AttributeError: 'NoneType' object has no attribute 'jpegquality'

I'm not sure where it should be stored, but we should also rename it because it would be interesting to also use it to carry x264/vpx quality.
