REST access log is broken

The REST access log is broken in several ways:
(REST-REST-ServerWorker-6-1) /127.0.0.1:42054 [54208501] "GET /" 404 0 13 54208501 ms
(REST-REST-ServerWorker-6-1) /127.0.0.1:42054 [54261112] "GET /rest/default" 200 0 51 54261112 ms

Todo:

• remove the thread name
• only print the remote address, without the initial / and the port
• fix the processing time, and print it only once
• print the request time using an appropriate format: [10/Oct/2000:13:55:36 -0700]
• use a nicer logger category instead of the class name of the logger
• print the user principal
