get files to point to .bik files instead of .png files

[pcbun]

Do never think that everything is included in ui and lua file. Just the very simple script, how do the game process the number of troop we choose from "buy_form.ui"? I can tell you, you can find no script how it work. And most from .ui I think is process by the kb.exe itself but not by .lua file. So I think you cant add any bik file by just simple editing lua file and ui file.
