Enhancements for Bookmarks

Adds a small link (a "+" or "-") next to each bookmark label on Google Bookmarks (http://www.google.com/bookmarks) to allow you to easilly add or remove labels from a query. This allows you to quickly and easily broaden or narrow your search within Google Bookmarks so you can find the most relevant bookmarks.

NOTE: On March 23, 2010 a major overhaul of Google Bookmarks was released. This included changes that broke most of the functionality of this extension. At the moment, its only function is to this extension still performs is to add a button to the toolbar that allows you to quickly add the current page to Google Bookmarks (same functionality of their bookmarklet).
