removed jekyll's paginations

First, it supports only one page path, so /ru/blog and /blog will have different
view. But there is a plugin jekyll-paginator, but it seems doesn't work and
github doesn't support an additional plugins.
Second, paginator doesn't work correctly with pages with different tags
(e.g. en and ru).
