Update to LanguageSupportPageNames so that it now supports use with URL segments.
Update Modules.php init() loader to support dependency load order for autoload modules. Now if an autoload module says it 'requires' another autoload module, ProcessWire will ensure that dependency is autoloaded first. This resolves issues with modules like LanguageSupportPageNames autoloading before LanguageSupport.module.
Update the $page->viewable() method to support $page->viewable($user), where $user is a User object, effectively providing a "viewable by user" capability.
Update the MarkupPageArray::renderPager() method to support URL segments with paginated URLs.
