Bookmark tags

Extension provides some additional functionality compared to default bookmark manager.

This extension allows you to do following things:

* add tags for any bookmark
* search bookmarks by tag, folder or title/url words
* bulk bookmark operations (open bookmarks, move them to folder, add or remove tag)
* find potential duplicate bookmarks
* show all used tags

Unlike many other extensions, this one uses default browser's bookmarks storage and handles tags as part of a title.
So it is possible to add some tags when creating new bookmark by just writing several #tags to its title.
