gnome-terminal: Improvement/Suggestion: Borderless multi-tab UI

This is an Improvement/Suggestion only for multi-tab UI.
I suggest to increase a tinny bit the margin below the tabs, add a line separator, and completely remove the right, left and bottom margins. This would make my beloved terminal a sweet borderless multi-tab window.
