Updated patch, against r53416

Updated patch. This moves all robots handling to a new
Article::setRobotPolicyForView (reborn from Article::getRobotPolicyForView ),
which uses array_merge to build a single policy from the various layers of
config.  This has the nice freebie that you can now say something like:

$wgDefaultRobotPolicy = 'index, nofollow';
$wgNamespaceRobotPolicies[NS_USER] = 'noindex';

And the 'nofollow' attribute will be inherited from the default policy, which
would be expected behaviour.  Currently the policy would be lost and the
hardcoded default of 'follow' would be used... :(

The patch also cleans up Article::view() a little, to avoid the fourfold
duplication of the do-this-when-the-body-has-been-constructed section; prompted
because the call to setRobotPolicyForView() is moved there, so it has access to
the parser output (which is now stored as a member variable $mParserOutput,
rather than discarded) to check for __NOINDEX__ tags.  

I've also encapsulated the "do we allow __NOINDEX__ tags in this namespace"
logic in Title::canUseNoindex(), so it can be called from both
Article::setRobotPolicyForView() and the Parser. This makes it trivial to
resolve bug16979, which I've done in this patch; the modifications to
Parser.php aren't strictly necessary to resolve *this* bug, but it's quite a
nice (and useful) change.  

My first efforts at the change involved using the page_props table, which might
still be a good idea.  This led me to improve the documentation for
$wgPagePropLinkInvalidations, which I've left in because at the moment it's
totally rubbish.
