more docs and info links

Added some info links to russian articles about CQRS, also added 3 books about DDD, i've found them extremely useful, since they have some good examples, especially first one which is showing complete project (simple) development with DDD. 
Infoq DDD quickly book is placed before Evans for the reason that it is only 100 pages and is great start for those who want to learn about DDD more, since it is hard to read BBB at first )
