1.30->1.5 There are both new files, and new constants defined in old files.

I was intending to add Portuguese to my English and Spanish site but decided against it in the end, but I updated the files on this site to work with 1.39 and put them on sourceforge to encourage contributions from native speakers. No-one showed any interest in completing so the files are still there, unchanged.

While they will mostly work with 1.5, they need to be compared to the english 1.5 files and the corresponding new files and constants must be added to the fileset.
