Translation into German

[xorond]

i'm mainly writing the code in english now. we will want the user interface and the command line interface to be optionally switchable between english/german, so some parts will need to be translated.

i will take a look into how we can achieve this in a semi-automatic way (automatically extracting strings from code, putting them in a file, translating the strings in this file manually, and automatically replacing the english/german strings during runtime).

i'll write here when i find a decent way of doing this.
