Build 0037-38. Corrections with methods.

 - isCollide method in the Snake.class was improved. No it works correctly.
 - collideWithCell method int Logic is shutdown - any movement creates GameOver. Maybe checking should start from the second cell, and skip the first one.
 - There was a bag, when food appeared on the borders, snake was not able to eat it. Decreasing of possible values of coordinates should solve this problem
Build 0039 - 0040

Build 0039
 - CollideWithCell method checked all cells after a third. Only from this cell snake can bit herself

Build 0040
 - Created method addNewCell, which does not take parameters. It adds the cell in the end of the snake.
 - Test changes - Space button works to create a new cell, using addNewCell method.
