Rearranged the templates around CMSPagesController_ContentToolbar and
uncommented the toolbar from the pages list view so the add new button
would be included with including actions that aren't applicable to the
gridfield.

Was inferred by the containing file previously,
which is deprecated behaviour, because it obscures
the fact that renaming an template file or copying
template code will change the context of the translations.
While it would be nice to use shorter and more readable namespaces,
this change would remove all existing translations.
Since there is no (easy) migration of entities to a new namespace,
having verbose template code is the lesser of two evils.
