Bookshelf update

I have added another good reference for Russian translator's bookshelf. Unlike Milchin it contains no typographical rules, but includes the exhaustive description of every possible use case of every single "official" punctuation rule, which may be useful in QA battles. This particular edition was issued to revert some notorious changes that were introduced in previous version, and inscribed illiteracy into norm. Format: FB2+DOC.
