Not all old code works clear and it needs to fixed.
Also I fixed bug with adding new post in 2+ page.
Added FIXME comments in app.js. Added some changes in routes.

In paginationHelpers we need to fix nextButton disabling.
In searchRoute we need to fix serialization and deserialization.
Deleted old ember libs. Deleted old Router in app.js.
