Additional log level - verbose

[oculushut]

I have made some changes to one of my branches to allow more detailed logging.

I would like to add a verbose setting to the main code base which will cause the server to log to server.log each time one of main client accessible methods are called (e.g. logon, move etc).

I will leave the default as "info".

I think this may be useful for future debugging and when trying to replicate live problems.

Worth doing?
