DlangUI translations

[stunaep via Digitalmars-d-learn]

I am wondering how to use other languages and how to NOT use 
other languages. I have all of the UI of my program translated to 
Russian, and I have the languages loading from the resource 
files, but I have no idea how to switch the language to Russian. 
Also, when adding file names to a StringListWidget, it shows 
"UNTRANSLATED: " before every file name, which needs to be 
removed.
