[Xfce-i18n] Done Re: pt_PT translations

[Mike Massonnet]

Hello Nuno,

I applied the patches, tho they were a bit weird again.

-*- xfce4-time-out-plugin had the content of the file twice
-*- xfce4-smartpm-plugin same here, but the header of the po file (the
    comment) wasn't repeated

Thanks,
mike
