No Ukrainian options in Language list

You've made great module. And it works very good.
But it's very sad, that there is no my native language in the language list.
I use TynyMCE but Language set is common for all Visual Editors.
I've checked there is no lang "uk" neither in 5x version nor in 6x.
I've attached diff patch to wysiwyg.admin.inc file. It's very simple - just to add 'uk' (Ukrainian) to the list.
Will be happy if in the new versions there will be native support for Ukrainian in WYSIWYG.
Thanks.
