Remove old unused code

There is nothing more permanent the temporary things. Don't be lazy! Remove old unused code. It doesn't do anything but requires support. You may say that it may be required in future. Heh... I sure that everyone uses version control software. There should be no problem to find desired odler version of code and get removed code piece.

Conclusion: Current system version should contain minimal required amount of code. There is not place for old and unused code.
