Article chapters added: “Software development process” and “Plans and priorities”

There are two completely new chapters added to the introductory article on Sivelkiria OS: “Software development process” and “Plans and priorities”. Also, the following sections were updated and expanded: “Security”, “Disadvantages of proposed solution”, “Interacting with other systems” and “Platform coverage”.

I am pleased to thank dear V. S. for his very useful feedback these changes were based upon.

Also, the article will soon be expanded with examples of how currently popular programs will look on Sivelkiria OS.
