a Debian user asked if it was possible to change the tab color when there is background activity (a bit like irssi, or as the initial bug reported said, multi-gnome-terminal).
It would be a nice feature to have.

Here is a patch to do that. it doesn't allow for configuration (color, timeout) yet, and sets the background tabs that have activity to red for two seconds.

Third revision: avoid setting the activity flag on the active tab (so that it doesn't get highlighted when switching away from it), and reset it to FALSE when activating a tab.

I've noticed that all background tabs get activity when resizing the terminal. The attached patch fixes that.
