1. Background navigations listener has been added. To see its actions open extensions's background page (in chrome tab "Extensions"), in console output you can see localStorage state. Attension! Monitor incorrectly tracks changes when you open 2 or more tabs with the same url. Also navigations using ui elements(as clicking on some bookmarks) that start from google chrome start page do not tracked. These 2 problems will be solved later.
