Minecraft EULA improvements (German)

These are suggestions for the German version of https://account.mojang.com/documents/minecraft_eula

General issues

1. Often the words "unfair" (same in English) and "vernünftig" ("reasonable") are never really exlpained and more than vague.
2. Statements are repeated multiple times, for example under which conditions you might use the game. This is definitely not needed, makes it only harder to read and increases the size for no reason.

Specific issues

1. Abbildungen oder Beiträge, die vermeintlich von einem Moderator stammen

   How and why does Mojang determines that? That is the task of the server owners.
