Fix user config template and load configuration before preparation of arguments

In the first release, all language packs except for the English language pack have been erroneously disabled by the user configuration template (which is generated, if no user configuration is found). Now, no language pack is disabled in this template anymore.

Furthermore, the configuration content, which may include "default arguments", has been loaded only after the preparation of arguments. Hence, these "default arguments" have not become active. This is fixed too.
