bug#904: [patch] russian-typewriter input method does not follow actual layout

I suggest to install this patch to close bug#904.  I confirm it implements
a layout used on real typewriters.

However, the layout it replaces is useful as well.  So I suggest
to move the current "russian-typewriter" layout to its current alias
"cyrillic-jcuken" (thus avoiding tricks employed to define the input
method's alias).

Installing this patch also requires updating `input-method' properties
in lisp/language/cyrillic.el (and removing some FIXME's).  I believe this
would clean up the mess.
