Fix for Bug 45195: Cannot close terminal emulation with Ctrl+D anymore (major)

[Ellis Whitehead]

Hi,

Here's a patch to TEWidget to make terminal emulation work the way that the 
user in the bug report (http://bugs.kde.org/show_bug.cgi?id=45195) would 
apparently prefer it: specifically, that when Ctrl+D is pressed from within 
the terminal emulation frame within konqueror, it exits the emulator rather 
than duplicating the konqueror window.

This means that Ctrl+D will always be overridden when TEWidget has the 
keyboard focus, no matter what program it's embedded in.

Commit, or no?

Cheers,
Ellis
