Use domain as citation title if no document

Partly a reaction to fce1f2c, which made icons overall smaller.

This is a bad way to address places where what we really want is the
icon as a badge on an element that has text next it. We have special
styles for buttons, but not for other scenarios. Icons should be
resized based on semantic styles for their use rather than globally.

The config blocks should be after the declarations of services, at
least, so that they can decorate services.

Bump the number of annotations loaded per request to 200

The overhead associated with a single search call is high enough that
loading only 20 annotations at once is too little. In a naive test this
reduces the time take to request about 300 annotations from 5 seconds to
about 800ms (which, IMO, is still far too slow.)

An annotation's document.title is used as the citation when displaying
an annotation. If this is an older annotation that has no document, fall
back to using the domain as the citation title instead.

Fixes #1542

Remove Dockerfile entrypoint

Handle internal server errors in the registration form

Add a test for how the frontend handles an invalid response from the
server when trying to register a user account. This happens if the
server has an uncaught exception.

Merge branch '1755-handle-internal-server-error-in-registration-form' of github.com:hypothesis/h into 1755-handle-internal-server-error-in-registration-form

Conflicts:
	h/static/scripts/account/auth-controller.coffee

Add a frontend test for when the server returns an error response with a
"reason" but no "errors" in the JSON-object response body.

When catching a non-JSON error response from the server, when trying to
register a user.

Hide orphan annotations in the sidebar

This fixes #1755: no error is shown on the client side when an attempt
to register an account receives a 500 Server Error response.

The failure() method in AuthController gets called and tries to do
{errors, reason} = response.data, but this raises a TypeError because
response.data is undefined (because the response didn't have a valid
JSON body), so the client crashes as well.

The fix is to catch this exception on the client side, and show a
generic error to the user.

Improve packaging, bundling and module boilerplate

Prevent negative interactions with module systems present in injected
pages and refactor browserify interactions with angular to increase
CommonJS accessibility / legibility and isolate angular module system
boilerplate.

- Avoid issues due to mis-detected module environments

  - In the injection script, load only Annotator and jQuery in the
    global scope and then both removed with `noConflict()`. Both are
    loaded with browserify-shim, which prevents jQuery from registering
    itself against require.js, if present (fix #2026).

  - Be explicit about registration of common cross-frame components
    (fix #2090).

    - Lift angular glue into app.coffee. Individual components are
      exported as CommonJS modules.

    - Lift Annotator glue into bootstrap.js (renamed hypothesis.js).

- Break up all modules that contained multiple services/directives/etc,
  such as the formHelpers and uiHelpers modules, as well as catch-all
  files like services.coffee and directives.coffee. For a summary of
  these movements see the bottom of this commit message.

- Rename all services, dropping the -service suffix, to match their
  injected names. This is consistent with how directives are being
  treated, and controllers as well (controllers are registered and
  injected done with the "Controller" suffix).

- Move Annotator subclasses into the annotator subdirectory. This
  change avoids having `Annotator.Host` clash with the `host`
  service and makes it easy to glob dependencies in assets.yaml to
  minimally rebuild either the app or the inject.

Move CSRF handling into a tween

Scroll to login form when clicking sign in link

This fixes an issue that if the login form is already shown but the
iframe is taller than the window and scrolled down so that the form is
out of view, then clicking on Sign in would do nothing. With this fix,
clicking Sign in scrolls the iframe up to the login form.

AppController listens to 'beforeAnnotationCreated'

By doing that it catches newly created annotations and clear the current
