Allow truncating accesslog

We are trying to look at the accesslog log file, but it has grown to over 900 MB in size. Please add the option to configure this file to be pinched off and a new file opened at a certain size, foor example every 50 MB or so, configured up to 20 (or 30 or 40 or however many configured) files before the oldest is overwritten.
