[Uim] easy hack to enable Yen sign for Japanese keyboard

[Yusuke TABATA]

This patch is a quick hack for long standing problem of Japanese kana-input.
I know this is not a good solution, however
 (1) This hack only affects on gtk+ immodule with Japanese keyboard
     -> please confirm.
 (2) Correct solution may not be available in near future.

What do you think about this?
