Made some more changes to the way namespaces are handled, for optimization purposes. This is a bit of a structural reorganization: $paths->pages is obsoleted in its entirety; calculating page existence and metadata is now the job of the Namespace_* backend class. There are many things in PageProcessor that should be reorganized, and page actions in general should really be rethought. This is probably the beginning of a long process that will be taking place over the course of the betas.
<!-- Stuff related to toolbars and clickable buttons.
The plan was to use this on the toolbar for most pages. Never made it into the release,
but still provided as an otherwise-unused component for plugins to make use of.
