Implement config for check-redirect and magic word.

Browse Source 
Added two new configuration variables, $wgLinkTitlesCheckRedirect and
$wgLinkTitlesEnableNoTargetMagicWord, that can be used to increase
performance. If both are overridden to be false, the target page content
will not be fetched from the database to check for redirect or the
occurrence of a magic word, which saves a lot of time.
