patch for per-namespace boilerplates
A customer requested to be able to define a different set of boilerplates per namespace.
I implemented this by using Mediawiki:Multiboilerplate-<namespacenumber>, for example Mediawiki:Multiboilerplate-12 contains page templates for the help namespace. The main namespace still uses Mediawiki:Multiboilerplate (without "-0").
Additionally I introduced a new config variable
$wgMultiBoilerplatePerNamespace
to enable the per-namespace boilerplates (default is disabled for backwards compatibility).
The patch for MultiBoilerplate.php is attached.
