[Uim] GTK+ version dependency

[TOKUNAGA Hiroyuki]

Hi,

Uim consists from several parts. i.e.

 * libuim - core library, depends on iconv and libc only.
 * GTK+ immodule - GTK+ bridge, require GTK+ 2.2 or higher
 * GTK+ helpers - toolbar, switcher, require GTK+ 2.2 or higher
 * (Qt immodule and Qt helpers are not merged yet.)
 * uim-xim - XIM server, require libstdc++
 * uim-fep  - front end processer require nothing

If I remember correctly, GTK+ helpers of uim 0.4.5 requires at least
GTK+ 2.2. But already GTK+ 2.6 was released, I think GTK+ 2.4 is popular
enough to depends.

If no one is opposed, I'll make GTK+ helpers to require GTK+ 2.4
tomorrow. (If you have an objection and I already made such change,
don't worry, please send me the objection. We can revert easily.)


Regards,
