Standardise logs

[jools772]

At the monent I have several logs from deluge, one from the daemon (with loglevel less than WARNING), one from the web-ui (loglevel less than WARNING). ThenI also have a separate log from the system daemon, that logs everyhing else, so that would be above WARNING.

Also, the daemon and web-ui logs are erased when the application restarts. I have a kill-switch when the vpn goes down, so unrfortunately these restarts happen quite frequently, and I don't know whether they are network downs or application crashes. WOuld be ncie to have one unified log for the daemon at least, that appends and not writes to the log file.

Also, would be nice to also have the date and not only the time preceding the log message.
