Terminal widget should use bashrc profile

At the moment, the terminal widget in the update-notifier program (and in synaptic as well) uses a standard black terminal with a white font.

The gnome terminal and other terminal emulators use the bashrc file in the home directory to customize the look of the terminal. Although the terminal widget in the update-notifier application is not interactive, it would be nice if the terminal followed the bashrc profile, or at least followed the gnome theme style that was currently in use. This means using the selected system font etc.

Although the terminal widget is hidden by default and this may not be a huge deal, I think making a gtk terminal widget that uses the user's bashrc file would be great for a more consistant user experience.

It would be even better is the widget could use transparency in composite environment like gnome-terminal to make it semi-transparent.
