Improvements to Russian version + Makefile + link in README

* Fixed page breaks and code split between pages (in Russian version), compressed text in couple locations so that it doesn't pagebreak.
* Added link to Russian version in README and reformatted README to use 80 character lines
* Makefile now builds both RU and EN (`make`, NOTE for this you will need both pdflatex and xelatex) or you can choose `make english`, `make russian`. Using nonstop mode for pdflatex so it won't stop mid-build asking for user input.
* Translator name (me) added to Russian intro page.
