GKsu 2.0.0

GKSu is a library that provides a Gtk+ frontend to su and sudo. GKsu project supports login shells and preserving environment when acting as a su frontend.
It is useful to menu items or other graphical programs that need to ask a users password to run another program as another user.
Enhancements:
- Since the last 1.3 version, this is the first high profile stable release of the gksu application.
- Together with the changes of libgksu, gksu now is able to use a global gconf setting to use su or sudo as the backend, handles "wrong password" better, and other things.
- An optional nautilus addon was added, which adds an "Open as administrator" menu item to the nautilus context menu for various files and folders.
- This menu item will open that file using the application that handles its type by default using gksu.
