(Windows) UI language set to current Date/Time Format instead of OS Display Language

[Brum]

In the Windows build, UNetbootin chooses its default display language (without command line parameter override) to match the currently set Windows Date/Time Format:
http://windows.microsoft.com/is-is/windows/change-dates-times-currency-measurements-display

This causes UNetbootin to display in the Date/Time Format language instead of the OS Display Language:
http://windows.microsoft.com/en-us/windows7/install-or-change-a-display-language

Example:
Windows 7 with English (US) Display Language and Croatian Date/Time Format causes UNetbootin to run with Croatian UI Language.
