Knowledge Base links updated

The site is not available as for know but I am
updating its original links according to what
I have found in the printed version of the book:
http://tinyurl.com/o2xs2a4

The pattern corrected automatically this way:
./replace.py -r '\/knowledge-base\/index\.phtml\/' \
'http://www.faqts.com/knowledge-base/index.phtml/'
Links update to UserDict and copy modules

./replace.py -f '/doc/current/lib/module-UserDict.html' \
         'https://docs.python.org/2/library/userdict.html'
./replace.py -f '/doc/current/lib/module-copy.html' \
         'https://docs.python.org/2/library/copy.html'
