Firebug 2.0 with new debugging engine

Firebug 2 went through a face lift in this version. World class designers have been working on the new theme and the user interface is now clean and more intuitive.

Firebug 2 introduces many new features and bug fixes also because we completely removed dependency on the ancient Firefox debugging engine (aka JSD1) and incorporated new debugging engine known as JSD2.
