Added gettext to the login page and the students/ folder with some
nl_BE po-files in the locale/ folder.
Breadcrumbs to be done at the end.

Use

// Setting up gettext.
$locale = "nl_BE";
putenv("LANG=".$locale);
setlocale(LC_ALL, $locale);
$domain = "webpa";
bindtextdomain($domain, "/path/to/local");
bind_textdomain_codeset($domain, "UTF-8");
textdomain($domain);
