Bash completion

I sent these in to the bash_completion people but it probably takes a while to get through. I haven't added for all the apertium-* programs. Put the files in /etc/bash_completion.d/ or wherever (see http://www.debian-administration.org/article/An_introduction_to_bash_completion_part_1 ). Probably it'd be simpler to use compleat instead.
