[request] Add Althttpd log format

[xoich]

Hi, Althttpd is the HTTP server made by the author of Sqlite and serving sqlite.org. This is the log format:

time-format %H:%M:%S
date-format %Y-%m-%d
log-format %d %t,%h,"%r","%R",%s,%^,%b,%^,%^,%^,%^,%D,%^,"%u"

For confirmation you can find the format here (search for Log record files)
