#2809 German language only within help

[Thomas Koch]

Using 'squirrelmail-webmail-1.4.22.zip' together with the translation file 'de_DE-1.4.18-20090526.tar.gz' (I could not find a more actual file fitting 1.4.22) only the help is translated into German. The folder views and compose view are still English.

OS is Ubuntu 12.04.2 LTS, Apache version is 2.2.22 and PHP version is 5.3.10-1ubuntu3.6.
