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.

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.
