Subject: [PATCH] API: Fixing issue mentioned on bug 16129 comment #3: for
 certain inputs, action=parse dies with an internal error whining about
 $wgTitle not being set in OutputPage::parse(). This commit works around this
 by setting $wgTitle, but the parser and its friends should really leave
 $wgTitle alone, because people might want to parse non-$wgTitle titles, which
 the Parser::parse() docs suggest is possible (and it should be), but
 apparently isn't.
