Updated icons for toolbar. Cleaned up Icomoon session file to reduce its size and bring it up to date with the newest version of the Icomoon app.

 * Updated dom-text-mapper to 3fb30bee (master branch)
 * Updated Annotator to 631c1345 (typed-packaging branch)

These are all internal DTM / Annotator changes.
The communcation about DOM changes has migrated from method calls
to events.

See also https://github.com/hypothesis/dom-text-mapper/issues/14

When hovering the mouse over a visible highlight, add a drop shadow to the annotation card in the sidebar.

Fixes #918.
Also fixes #957.

 * Updated Annotator to 3d4ae840 (typed-packaging branch).
   In this version, the `noDocAccess` option has been removed.
 * Added the required (noop) overrides to regain the same functionality

Also did some cosmetical changes.

Fixes #953.

 * Update Annotator to bbad33fe (typed-packaging branch),
   which has some adder-related tweaks/fixes.
   (More sane encapsulation of the `canAnnotate` behavior,
   following suggestions from @gergely-ujvari)
 * Copy Annotator's changes to our overrides:
   * In `onAdderClick()`, set `inAdderClick`
   * In `onSuccessfulSelection()`, return false when annotating is forbidden
 * Upon building the channels between the guest and sidebar,
   synchronize the enableAnnotating state.

Really fixes #949.

 * Update Annotator to dd6f102d (typed-packaging branch)
   * Several internal fixes, tweaks and cosmetic changes
     (Now it's fully functional in Stand-alone mode, again.)
 * Follow Annotator API changes
   * `noMatcing` option renamed to `noDocAccess`
   * `ignoreMouseUp` option renamed to `canAnnotate`,
      and the semantics got inverted
 * The bridge plugin now propagates the 'enableAnnotating' events
 * Added an `isEmpty` method to the draft service
 * When editing/replying/canceling/saving in the sidebar,
   enable/disable annotating.

Fixes #949

 * Add support for activating/deactivating HLs in batch mode
 * Cosmetic changes (change the names of some doc access strategies)

Fixes #807.

 * Replaced the obsolete ng-bind-html-unsafe directives in page_search
   with the new mechanism
 * Fixed a bug in page_search when quotes were not shown in detail mode
   (ng-hide / ng-show mixup)
 * Changed the handling of the "show diff" checkbox to be more consistend
   between search and viewer templates

Touches upon #807
Fixes #947

AngularJS has killed the ng-bind-html-unsafe directive, which we used
for displaying the visual diff. (See here: https://github.com/angular/angular.js/commit/dae694739b9581bea5dbc53522ec00d87b26ae55 )

Update the code to work with the new way.

Fixes #807.

 * Update annotator to 4f0961d3 (typed-packing branch) with bugfix

Fixes #942.

To achieve this, updated Annotator's TextAnchors plugin to 989382f5
(typed-packaging branch).

Closes #422

 * Updated dom-text-matcher to dd5d2eaf (master branch)
 * Updated Annotators' FuzzyTextAnchors plugin
   to e2e98dd8 (typed-packaging branch)

Fixes #941.

This new version replaces PDF.js's top-level text extraction logic
with a manual override, in order to try to avoid concatenated words.

Fixes #940.

Incorporate the latest work done on Annotator's typed-packaging branch.

There are almost no H-related changes here; it's only about Annotator internal changes.
(Packaging and cosmetic fixed, and a few smaller bug fixes.)

Follow the packaging changes.

Followed packaging changes. (New plugins, etc.)

 * Update Annotator to 62c94fc
   (typed-anchors-final branch, replacing maintence for now)
 * Updated guest.coffee

Fixes #929.

Introducing typed anchor support

 * Updated Annotator to de4c0dfc (maintenance branch), which has
   typed anchors support merged.
   See https://github.com/hypothesis/annotator/pull/18 for explanation.

The H specific parts:

 * Following Annotator API and packaging changes
 * The heatmap got a lot trickier. Since it can no longer make any
   assumption about the actual implementation of the highlights and
   anchors, now it does not rely on any data inside them. That includes
   the start and stop character offsets, too, which was previously used
   to find the nearest anchor for the up/down arrows on.
   We can't assume that all anchors have that data.
   Unfortunately, the Y coordinate is not always available, because
   the required part of the DOM might not be rendered yet.
   So the only data we have is the page number. (All anchors have page
   numbers). In the first phase, we only collect the anchors from the
   nearest page. Then we go there, to assure that it's rendered.
   When all the anchors have been realized, we select the nearest one,
   and actually scroll to it. This way, we can make it work with
   all kinds of anchors/highlights.

This version fixes yet other race condition during initialization.

Fixes #892. Hopefully, it really stays dead this time.

This version fixes another race condition during initialization.

Hopefully fixes #892 for good.

This version delays the PDF scanning until the document is ready.
