utf-translate-cjk-mode

[Dave Love]

There was a good reason for not doing this:

        * international/utf-8.el (utf-translate-cjk-mode): Minor mode,
        replaces variable utf-translate-cjk which must be set via Custom.

The point was to make sure it was set through Custom so that it was
consistent with the language environment through a Custom :set-after.
That's still not good enough, since customize doesn't act on custom
dependencies as I think it should, but it helps.
