Record approximate time-in-queue info for "realtime"

Add some timers to the streamer code

Disable a contradictory pep257 rule

Adds hashtag #annotated to web intent

When displaying a standalone annotation page for replies, display the
entire conversation thread which that reply is in, including the
original annotation.

Previously standalone annotation pages for replies were broken because
only the reply itself was fetched, the the existence of the top-level
annotation was inferred from the reply's `references` field but because
it was missing, a blank "Message not available" card was shown instead.

Showing the entire thread fixes this problem and also allows the user to
see the complete context of the conversation.

Also refactor the tests to be less tied to the implementation details of
the class and expressed more in terms of what the view does from a
user's point of view.

Fixes #3367

Add a NIPSA service to replace h.nipsa.logic

Allow admins to toggle specific features for a features cohort

`selections()` tried to listen for a 'ready' event on the DOM Document
object. The 'ready' event however is jQuery-specific however so that
never gets triggered.

Instead change the `selections()` function to perform an initial check
for a selection on the next tick and emit a null|DOMRange.

Fixes #3452

Make the styling of quoted snippets of the page consistent with the
styling of block quotes in annotation bodies.

The styling for `<del>` and `<ins>` elements in quotes has been removed
because it is not currently used.

Fixes #3435

Load annotations from DB for /api/search

Set the annotation cursor to a pointer for annotation cards to indicate
that it is clickable (it scrolls the page to that annotation) except for
the body which has a text cursor to indicate that the text is
selectable.

Several places in the <annotation> component assumed that the `tags`
field was an array, as did <tag-editor>. The `tags` and `text` fields
are always set by the server for annotations received from the API but
are not set by Annotator when creating new annotations in the page.

It would be better to initialize all of the required fields for
annotations when they are loaded into the app rather than in the
<annotation> directive. For now however keep the initialization of all
required fields in the same place.

This fixes an error when saving new annotations.

Do not use query property in Feature.{all,remove_old_flags}

Extract tag editor into separate component and update ng-tags-input

This fixes some issues with Angular 1.5.x.

Fixes #3324

As part of an effort to simplify the <annotation> directive and make
testing easier, split this out.

Add options page to extension, allow disabling badge

The idiomatic way to create derived data structures from data in the
Redux state store is to do:

  derivedData = transform(select(store.getState()))

Where the `select` function extracts the relevant fields from the state
and the `transform` function then computes the derived data. Both
`select` and `transform` can be trivially memoized to avoid unnecessary
recalculations.

This simplifies `root-thread` by avoiding inheritance from EventEmitter
and in future will make it easier to avoid rebuilding the thread if none
of the relevant application state has changed.

Do not use query property in User.get_by_username

Extract timestamp out into its own component

The util.createDirective() test helper assumes that directives have
controllers and reports an error if it fails to find one.

The simplest solution is just to add no-op controllers to the affected
directives.

This makes it easier to test the refresh logic directly and decouples it
from the rest of the annotation display.

This brings support for lifecycle hooks which get called when components
are mounted, when their inputs are changed and when they are destroyed.

See https://github.com/angular/angular.js/commit/9cd9956d

Angular patch releases have historically been pretty safe WRT breaking
changes, so this loosens the version strictness slightly.

Rather than imperatively adding a 'keydown' event handler in the
<annotation> link function, use `ng-keydown` to set up an event handler
instead.

With this we no longer need a link function.

Persist in-place mutations of annotation tags and extras

Do not use query property in Blocklist model

Remove path for local pdf files.

Currently, when annotating a local PDF, the `file://` URL will be submitted to the server.
It is not appropriate to submit local file paths to the server.
Since entries in document.link should be URIs, omit the URL in the case of local files.

Add Hypothesis-driven property-based tests for query builder

Use PDF fingerprint as primary search URI for PDFs instead of url.

The `actual` value is always the first argument to `assert` functions.

Also add an explicit separate test that checks that PDFMetadata
functions resolve immediately if the document is already loaded.

Consider the following situation:

- A PDF with fingerprint (F) exists at multiple URLs (U1, U2, ...)
- A user visits the PDF at U1 and annotates it
- A second user visits the PDF at U2

Prior to this commit, due to the way document equivalence for PDFs
functions, the annotations made at U1 will not be loaded, because the
initial search is made for U2 only.

(If the second user subsequently makes annotations at U2, and then
reloads the page, the annotations made at U1 will then show up, as the
association between U2 and F will have been made).

This commit improves the situation here by treating the PDF fingerprint
as the "primary URI" for the document, much as we treat <link
rel="canonical"> URLs as "primary" if we find them in an HTML page.

This means that the initial search will be made for the fingerprint F,
which will match the annotations made at U1.
