Extract core rendering functionality from the mw.popups.renderer and
mw.popups.renderer.article objects.
For now, render and show the preview when the user dwells on and
abandons a link respectively.
Supporting changes:
* Add mw.popups.wait, which is sugar around window.setTimeout.
* action.response -> action.result in the FETCH_END case of the preview
reducer.

Supporting changes:
* Remove the preview.previousActiveLink property from the state tree as
it's unnecessary.

OO.copy doesn't copy Element instances, whereas $.extend does. However,
OO.copy does copy properties whose values are undefined or null, whereas
$.extend doesn't.
Since the state tree contains an Element instance - the
preview.activeLink property - we need to use $.extend.
Add the nextState helper function which copies the current state tree
with $.extend and mixes in all updates manually.

If the user has abandoned the link or dwelled on a different link, then
don't make the API request.
Changes:
* Fix a bug in the linkDwell reducer where the activeLink was always
being set to undefined.
* Add the private fetch action creator.
* Make the linkDwell action dispatch the result of the fetch action
creator after 500ms.
Supporting changes:
* Make the link* action creators take DOM elements rather than jQuery
instances so that:
1. Testing whether the state tree has changed is an identity
comparison.
2. jQuery instances are constructed only when required.
* Document the ext.popups.Gateway type.
* Document the Redux.Store type.
* Rename the "previews-page-title" data attribute to
"page-previews-title" to avoid confusion.

Changes:
* Add sessionToken and pageToken properties to the BOOT action and
update the preview reducer.
Supporting changes:
* Move the mw.popups.createActions to ext.popups/boot.js so that Redux
is used in one file and the actions can be tested in isolation more
easily.

Reducers as a whole are a WIP, but this implements a baseline from which
to add more.
Changes:
* Create ext.popups.reducers to house all reducers
* Create reducers for preview and renderer state manipulation
* Create rootReducer by combining preview and renderer reducers
* Add QUnit tests for reducers
* Move action types into ext.popups.actionTypes
* Extract rootReducer from boot.js
