(svn r4105) - Feature: Add proper ISO-8859-15 <> LOCALCODE conversion. As the mess that is makefile can't properly support it at the moment, it is only available for MACOSX. Windows doesn't need FS conversion and I have no idea about OS/2 so it's disabled for them.

- CodeChange: Change the function GetCurrentLocale(). It returns the locale from some default environment-variables, plus a custom one defined as parameter. If all fail, it tries $LANG.
