bugfixes

- fix chrome rename bug (rename on chrome triggered "change" event which led to redundant thumbnails being captured)
- fix context menu bug which led to duplicate thumbnails
- fix thumbnail path issue for relative urls (leading / in url should be a path relative to the domain root)
- support for speed dials created via bookmarks manager in chrome
