ad532cdbaa Updated scheduler - now change_task and irq0 handler don't intersect so ugly. The code became more straightforward. By the way, it is also faster.

b37db20eb6 More correct build_ru.bat and build_en.bat 
Now kernel uses interrupt gates for i40 handler instead of task gates. 
So i40 handler TSS can be removed.
