Title: add back and enable extended logging capabilities

* request latency and dispatch timing
* user-agents
* usage of X-Forwarded-For: header over requesting IP if present

it turns the request log from:

`172.16.9.7 - - [23/May/2012:22:03:18 +0000] "GET /blah HTTP/1.1" 200 55`

into

`74.122.184.28 - - [23/May/2012:22:27:09 +0000] "GET /blah HTTP/1.1" 200 55 "-" "User-Agent" 47 47`
