Installing non English system languages

[Germano Massullo]

Since Fedora 18, all people speaking non English languages are
experiencing troubles in setting their system language without having to
manually install kde-l10n-* package. This is a problem for new
Fedora/Linux users.
I opened a bugreport years ago about system-config-language but the only
thing that changed, is that system-config-language is no longer present
in Fedora 20 KDE Spin, and even if you install it, it will not have any
effect on the system.

A new tool for installing system languages is an urgent need.
