This patch sets the basis for overriding key combinations that the terminal emulator should capture, even if they are assigned as shortcuts in the program. In this case, only Ctrl+D is overridden.

I leave further expansion of overriding to the discression the konsole/konqueror developers.  It's been suggested, for example, that all Ctrl+<key> shortcuts should be overriden.
