Add support for getting page template name in $pages->findRaw()

[Toutouwai]

Short description of the enhancement

It would be nice to be able to get the template name of pages in the array returned by $pages->findRaw(), maybe by using a syntax like template.name in the $fields argument.

Currently you can get the template ID by using templates_id in $fields but often the template name is preferred and that then requires the developer to do a separate step to translate the template IDs to names. It would be handy if findRaw() could take care of that.
