New way to translate ispCP

[raphael]

Ok, since r679 we will now be using .po files to handle the translations.
Many changes were made to the current translations so almost all need to be updated.

I imported the existing translations and converted them into .po files.
If you notice that there's a missing .po please tell me the language code of that translation, because there was one of the exising translations that didn't have the required info.

The source .pot is language-files/ispCP.pot
At the moment all the .po files are up-to-date to the current .pot

Malte/Benedikt: can any of you update the links of the website so they now point to the .po files?

I will try to finish the script that converts the .po files back into the A=B format by tomorrow morning.

NOTE: all the languages were imported automatically, and all those with msgid = msgstr were marked as fuzzy.
