Got ACL scope logic working again and began enforcing it. Breaking API change: assigning page title with $template->tpl_strings['PAGE_NAME'] will no longer work, use $template->assign_vars(). Workaround may be added later. Test for assign_vars method if compatibility needed. Added namespace processor API (non-breaking change). Several other things tweaked around as well.
<!-- 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.
