Bash-Bookmarks nga ArtBIT

This is a companion extension to https://github.com/artbit/bash-bookmarks

# What it does

It allows you to create and search through an external bookmarks manager (https://github.com/artbit/bash-bookmarks)

It registers a new 'bb' keyword that allows you to search for bash-bookmarks directly in the address bar.
`bb somesearchkeywords`

The extension will query the bash-bookmarks server for results and populate them in the address-bar suggestions.

It will also register a listener to whenever you add a new bookmark, and also save it in your bash-bookmarks.
