Quick Tabs Ported wót Kevin Jones

A user who switched from Chrome to Firefox said this addon was the thing they missed the most about Chrome. I checked it out and as it had very good reviews, I decided to port it to Firefox. I made a few tweaks to make the shortcuts customizeable in Firefox in the Options page. Note that for the time being, I have disabled the previous/next tab in history shortcut implementation, because it seemed buggy, until I can figure out what the problem is.
