[patch] Portuguese timedef

In Portuguese, the names of the days of the week are not capitalized.
Also there is always a dash before "feira" in the names of the days.
For example: "segunda-feira" and not "segunda feira" (which has a
completely different meaning).

x_fmt is not correct either. The date separator should not be a dot
but a slash. Example: 31/12/2005 if far more used in Portugal than
31.12.2005.
