[horde] Translation of Alpha

[joho at poolia.se]

Is there any point in doing a translation of the Alpha-packages? A lot of
work has obviously already been completed, but there are quite a few items
missing in the Swedish translation for Horde and its applications. I am not
too familiar with "po" and the likes, but found the .pot file which I guess
works too ;)

Since I've contributed translations in the past, I figured I might as well
do it again.
