[Gimp-web] books page update on gimp.org

[Bernhard Stockmann <devvv devvv de>]

hello web guys,

my publisher asked me if some german books&video trainings could be 
added to the www.gimp.org/books page? maybe also rename the page to 
"products" because there is a growing number of video trainings stuff 
(especially in the graphics area).

this page could be also linked from the "Help" menu in GIMP itself.

best regards,
bernhard
