(svn r27033) -Codechange: Generalize GetTextfile for multiple extensions

Browse Source 
- Instead of hardcoding the .txt extension in a printf string, it is
    now stored in an array of possible extensions. This array still only
    contains .txt, so behaviour is unchanged, but this makes it easier
    to add other extensions later.
