Enable localization/gettextification of $KeywordLinkRegexp. (Also, now
users not familiar with regex can more easily just edit the $keywords
array).

Added four new constants to define author and copyright link rel~s
used in html head. This makes it easier to run multiple wikis off of
one set of code.

Eliminated RECENT_CHANGES constant for RSS auto discovery because it's
another step to watch out for when running a non-english wiki. Now
simply defined as _("RecentChanges") in head.tmpl itself. Non-standard
wikis where the RecentChanges page has been named to something else
will have to modify this in head.tmpl (along with all other places the
word RecentChanges appears in the code, something that already would
have had to be done on such a wiki anyway).

Added a little more info and instructions to flesh out:
DEBUG, WIKI_NAME, ADMIN_USER, $DisabledActions, $DBParams, CHARSET.

A few typos and spelling mistakes corrected, and some text rewrapped.
