[Xfce-i18n] Last minute string addition to xfburn (pt_PT)

[Nuno Miguel]

 Hi again,

 Well, make this change:
 msgstr ""
"Falhou a iniciar o codificador: %s\n"
"\t(voltar à implementação básica)" to:
 msgstr ""
"Falhou a iniciar o codificador %s: %s\n
\t(voltar à implementação básica)".

 Thanks for caring of it. I'm a bit tired.

 Regards,
 Nuno Miguel
