EE7 - EE update remove translated files

[Caleydon]

When I want to load translations for Pro and Moblog built-in addons, I need manually upload translated files into Addons folder (in the EE core folder).

Path example for Slovak
/system/ee/ExpressionEngine/Addons/pro/language/slovak/pro_lang.php
/system/ee/ExpressionEngine/Addons/moblog/language/slovak/moblog_lang.php

After EE upgrade is whole "system/ee" folder replaced by the new EE version so translated files are removed.

Is clear that ALL translations (including built-in addons) should be stored out of "system/ee" folder - /system/user/language/YOUR-LANGUAGE/
EE should have the ability to detect and using translations if they are in the folder above.
