#713 more plots / chart types

[Gabriel Zachmann]

There are a number of other plots that i would love to
see in awstats neat presentation style:

1. The 2-dimensional month/day- and weekday/hour-plots;
   see http://www.hping.org/visitors/report.html

2. Some statistics (such as browser usage) would be
   much better presented using pie charts; for an example,
   see http://www.chiark.greenend.org.uk/~sret1/stats/

Best regards,
Gabriel.
