Title: Add colon to match common logger spec

Apache Common Logger uses a colon between the date and time, see http://httpd.apache.org/docs/1.3/logs.html#common and http://en.wikipedia.org/wiki/Common_Log_Format for examples. The lack of common breaks parsers that expect it (awstats is an example of this).
