* Updated dom-text-matcher to b253923d.
* Updated annotator to f85315e3.
* On annotations anchored with non-exact matches, don't automatically
  tick the "show differences" checkbox when there are only case differences.

Fixes #690.

Fixes #671

If propagation is not stopped then it'd collapse the results.
Fixes #682

Fixes #678.
Fixes #679.

Based on @tilgovi's suggestion the ng-click functions for saving/editing/deleting an annotation now have the $event argument and we stop propagating this event further so the collapse/open mechanism cannot react to them.
Fixes #609

Page search now interprets the tag search facet as a substring to look for in all tags.
Fixes #672

When the user runs a search, the sidebar switches to search view.
When killing the searchbar (with the x) afterwards, it switches back to viewer.
Leaving search mode triggers a route change watch,
which executes the necessary cleanup.

However, if we haven't yet started searching, only opened the searchbar,
and then kill it immediately (without running the search first), then
we are still in viewer mod, so no route change will happen.
Therefore, the cleanup is not triggered automatically.

So in these cases, we will have to trigger in manually.

Fixes #673.
Fixes #675.

PR for Unattached annotations (=comments) V1

Make the homepage bg a little darker

PR: Change when the sidebar is opened - v2

Introduced the updateViewer() method to do what showViewer() does,
except actually showing the sidebar.

Removed	the show() call	from showViewer().
Instead of this, I have manually added show() calls
to a few places. The result is this:

Don't automatically open the sidebar when
 * A new highlight is created
 * Heatmap is updated

But keep opening the sidebar when
 * Clicking on the heatmap
 * Clicking on a tab on the heatmap
 * Clicking on a highlight in the document

Close the searchbar when switching to a different view.

Fixes #643.

- Remove redunduncy from the code paths	for closing search
- Add some comments

Stream filters now handle both case sensitive and case insensitive searches.

Tags are case insensitive.

Fixes #654.

This reverts commit ec26ae5d89f66929935b8dc8f6ce4f62ab8dc40a.

uris can be case-sensitive

- Added a separate svg file (called comment_tab.svg) for the comment bucket.
- Reduced the space between the lower and the comment buckets
- If no comment bucket is shown, then the lower bucket is shown nearer to the bottom of the page.

The heatmap.updateHeatmap() was altered to create a separate bucket (similar to above and below) for comments. This bucket cannot be merged with the other buckets.

- Added 'references' for the whitelist for transferring this to the host frame.
- We're only applying the FakeCommentRange and HighlightRange for annotations which are not replies.

This sorted out the priblem mentioned in the comments of #115.

A bunch of things (including CSS styling) is still missing.

PR: Make all mentions of user names a link to the user stream

Now we can set case sensitivity for the streamer search properties. The clause evaluation in the FilterHandler class looks for this property and compares accordingly. The streamfilter.coffee was also extended to handle this new property.
