Log date and time of connection

[ahuillet]

Xpra doesn't log *when* a connection happens nor when it closes. Adding timestamps would be great.

[Antoine Martin]

As per ​logging-cookbook, it should be a simple matter of adding a formatter to all logging:

formatter = logging.Formatter('%(asctime)s %(message)s')
fh.setFormatter(formatter)

Two caveats:

• this applies to handlers, not loggers..
• winswitch may not be able to parse those messages correctly, this will need to be checked first (and push an update with a version check bump if needed)

done in r1172

And... it's never as simple as one changeset is it?

r1251 uses the old logger for commands like "version" and "info" so we don't break parsing!
