Enhance the access log format

Currently the access log outputs the following format:

/_utils/index.html METHOD: GET
/_utils/style/layout.css?0.11.0 METHOD: GET
/_utils/script/jquery.js METHOD: GET
/_utils/script/jquery.dialog.js METHOD: GET
/_utils/script/json2.js METHOD: GET

It would be useful if a standard format was used, the most obvious being: http://en.wikipedia.org/wiki/Common_Log_Format. A more adventurous alternate would be the MS IIS extended log file format: https://www.microsoft.com/technet/prodtechnol/WindowsServer2003/Library/IIS/bea506fd-38bc-4850-a4fb-e3a0379d321f.mspx?mfr=true, this is a customizable format which has the interesting time-taken field which is critical for performance analysis of REST APIs.
