Add Currently Viewing, Featured, & My Groups sections to group drop down

Replace $http with fetch in api service

 - Use `null` to indicate requests that fail in `expectCall` rather than
   0/-1.
 - Use 200 as the response from `POST /api/annotations` in tests to
   match the real response code from h.

* Add Currently Viewing, Featured Groups and My Groups sections
* Remove leave group icon
* Remove view group page link as there is no room for it in the UI
and
user’s are often clicking it accidentally.

* Remove ability to select groups that are not scoped to the page.


Simplify selector list items
Add active styles for toggle and list items
Only apply active background to group selector toggle
Refine dropdown toggle styles

This was missed in 11ac0e25.

`fetch` may reject if executing the request fails, eg. due to a
network-level error. Make sure that `store.apiRequestFinished` is called
in this case and modify an existing test to simulate this behavior
correctly.

Also make some minor comment improvements.

This header allows the h web service to associate API requests with
WebSocket clients, and thus avoid sending clients notifications about
their own actions.

This used to be set as a global header on all requests made with the
`$http` service. Re-implement this header but only for API requests.

Modify the Hypothesis API client to use `fetch` instead of $http.

There is one change to the interface of the "api" service which is that
failures no longer set a `response` property on the `Error` instance.
This functionality was not being used elsewhere in the client.

Move API activity state to store

Replace $http with fetch in api-routes service

Call `store.apiRequestStarted` and `store.apiRequestFinished` methods
when API requests start and finish. This causes the loading spinner to
correctly indicate whether API requests are in progress.

Reflect the loading state of the app reported by `store.isLoading()` in
the bar at the top of the UI, instead of querying
`$http.pendingRequests`.

This is part of the migration the Hypothesis API client away from
AngularJS's $http to `fetch`.
