Modeled similar to ConfigFactory, this lets skins
register themselves via a callback, allowing for
proper dependency injection.

Loading via $wgValidSkinNames is still supported,
but considered "legacy", not deprecated though.

Skin::newFromKey is now deprecated (and had only
one caller in an extension, which I'll update
afterwards).

-        * namespaces: Used for namespace tabs like special, page, and talk namespaces
-        * views: Used for primary page views like read, edit, history
-        * actions: Used for most extra page actions like deletion, protection, etc...
-        * variants: Used to list the language variants for the page
-        *
-        * Each section's value is a key/value array of links for that section.
-        * The links themselves have these common keys:
-        * - class: The css classes to apply to the tab
-        * - text: The text to display on the tab
-        * - href: The href for the tab to point to
-        * - rel: An optional rel= for the tab's link
-        * - redundant: If true the tab will be dropped in skins using content_actions
-        *   this is useful for tabs like "Read" which only have meaning in skins that
-        *   take special meaning from the grouped structure of content_navigation
-        *
-        * Views also have an extra key which can be used:
-        * - primary: If this is not true skins like vector may try to hide the tab
-        *            when the user has limited space in their browser window
-        *
-        * content_navigation using code also expects these ids to be present on the
-        * links, however these are usually automatically generated by SkinTemplate
-        * itself and are not necessary when using a hook. The only things these may
-        * matter to are people modifying content_navigation after it's initial creation:
-        * - id: A "preferred" id, most skins are best off outputting this preferred
-        *   id for best compatibility.
-        * - tooltiponly: This is set to true for some tabs in cases where the system

+        *
+        * Each section's value is a key/value array of links for that section.
+        * The links themselves have these common keys:
+        * - class: The css classes to apply to the tab
+        * - text: The text to display on the tab
+        * - href: The href for the tab to point to

+        * - redundant: If true the tab will be dropped in skins using content_actions
+        *   this is useful for tabs like "Read" which only have meaning in skins that
