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

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.

In the annotation template all user name is a link tag, with a href calculated by the new userLink filter.
Part of the solution for 523

Added a $routeChangeStart handle to the AppController which checks if we're to go back to the Viewer then it clears the searchbar and also clears the search query from localstorage
A solution for #643

We have added a few enhancements of tag-it,
but since we have stopped using them, there is no point in keeping
them. Therefore I am reverting to the unmodified upstream version.

 * Annotation currently being edited are added to the drafts
 * AppController.toggleHighlightingMode() checks for drafts before continuing
 * Fixes #628

CSS tweaks for tags, search, and other small things

 * Gave tags square corners, made them smaller, and slightly opaque.
 * Made tags left justified with text above and below.
 * The topbar is back to its original height
 * Old: The "share" url box no longer obscures the controls along its lower edge.
 * The space between different facets in the search bar is now a touch tighter.
 * Put highlight and lock icon on same line as username.

The old name of the facet scope was called area. In one place it was not renamed.

Restore edit reply delete for search

When making a Highlight in HL mode, switch sidebar view to single mode.

Fixes #641.

... to single view, showing only the newly created highlight.

(First attempt to fix #461.)

After changing the search term from a quote to another, the quote highlights were not refreshed

It broke when the annotation.text field was empty

It tried to apply regexps even when they were not set.

The editor itself was shown, but the surrounding div tag was hidden.

By default it showed and edited the highlightText property of an annotation not the text. Besides that the only thing to do is to rebuild the highlighttext after the text has been edited.

Fixed some page search issues. (See #617 for details.)

Work around situations when two simultenous parameter change caused two subsequent reloads.

The two cases were:
 * When forcd login is triggered by enabling Highligting Mode without loggin in first
 * Then logging off from Highlighting Mode (which also switches off highlighting mode)

Fixes #626

Not it has the same behaviour as the Viewer in this fascion.

The quote search terms are now highlighted in the annotations quote.

Fixes #625

- Only searches for quote in the top-level annotations
- Also if another search term is given it will only match for top-level annotations
- Quote hits are displayed in detail mode

Earlier the notification system swallowed some notifications for private annotations.

* Style the cursor above the notification counter exactly as above tri (w-resize and rw-resize, depending on sidebar state)
* Make it react to clicks
