Added LaTeX, Lisp and Dot to the supported languages of org-babel
Changed the key binding parameter of global-set-key to kbd to improve readability.
Removed lisp snippet that extracts the default browser out of gconf, since gconf is no longer the default configuration system of Ubuntu. I set the default browser to gnome-open.
Included melpa to the package-archieves
Activated ido-mode in org-mode
Added a new function called indent-whole-buffer and set the global key to "C-c i b". Source: http://emacsblog.org/2007/01/17/indent-whole-buffer/
