Subject: [PATCH] Yandex as default search engine

Unfortunately, Google has commercially gone away from Russia, where most users of ROSA Linux are located.
Quality of google.ru search results seems to be degradating a bit.

I understand that Google develops Chromium, and so it would be fair if they got some money from adverstisment,
but, firstly, they have themselves stopped all ads in Russia,
secondly, influnce of Google is a bad thing because they have to take part in the information war.

The patch "Functional new tab page with non-Google search engines" makes chrome://new-tab-page work.
Yandex's URL which is patched here does not allow to add new items in to the quick access list
and shows advertisment of the proprietary Yandex browser. I do not want users to install it.

A simpler solution would be changing chromium-default-config.json like
http://git.osmesh.ru/MOS/mos-panel-desktop/src/commit/0f02deea4f7da5ee186433cc71a7ba0193a8f52d/kometa-std-desktop-1.1/chromium.json
but it would make Yandex.ru be the default even for not Russian users.
