Updated .deb to 1.0.3. I just can't help tinkering!

Since there was some concern about xkbd, I decided to put the xkbd stuff within the python code rather than launching it separately via the xword.sh shell script. There is now a Preferences Menu option (with a check mark) to "Show xkbd". This option gets saved so that xkbd will show up (or not) when you start xword.

It still checks for the presence of /usr/bin/xkbd, and does not give you the Preference menu option if the binary isn't available.

So this really isn't a necessary update, but it makes it a bit nicer since xkbd is launched by xword. Also, this way the xkbd gets closed when the xword application exits.
