# Replaces links to:
# - Static content (images, CSS, Javascript...)
# - SDL Logo
# - Disable page-wide nofollow
# - Disable nofollow in <a> links (http://www.homelandstupidity.us/2005/05/23/nofollow-revisited/ , http://www.dofollow.fr/)
# - Links to non-existing pages (?WikiWord)
# - Links to pages with parameters (WikiWord?action=edit)
# - UserPreferences (don't trick people into local login)
# - TitleIndex with parameters (does not begin with "/cgi/docwiki.cgi")
# - RecentChanges with parameters (does not begin with "/cgi/docwiki.cgi")
# - Form 'action' field
# - "View" link in the top-right corner, so there's a link to the official wiki page
# - Get rid of search-engine unfriendly '/cgi-bin/' for remaining (i.e. local) links
#   Remain absolute (not relative) to handle Topic/SubTopic1 -> Topic/SubTopic2 links
