==Story
As a logged-in user, I want the ability to turn hovercards on and off once they are in stable, so that I can see the feature when I want to
==Description
Build logged-in user settings
==Acceptance Criteria
Users will be able to specify whether they want hovercards on or off via a section within the user preferences page. This will contain the following:
[X] The work should be done in the `mpga` branch.
[X] Section title: Reading Preferences
[X] Item title: Page Previews
[X] Subtitle: Get quick previews of a topic while reading an article
[] Radio button: Enable
-- Selecting Enable and Save will turn page previews ON
-- Selecting Enable and not saving will do nothing
[] Radio button: Disable
-- Selecting Disable and Save will turn page previews OFF
-- Selecting Disable without saving will do nothing
[X] Note: when hovercards are disabled for logged-in users, the “Enable Previews” link will NOT appear
[X] Must be feature flagged and off until move to stable
[] Allow user settings to be inherited by beta - if user had page previews enabled in beta, enable by default
[] Order - user preference for page previews should appear immediately after "Skin"

- if I'm a logged in user, the settings cog should link to the "appearance" tab in user preferences.

- the "enable previews" link on the bottom of the page will not appear
- this should be part of the rewrite branch
