Title: update julia code (improve 30 times)

As per http://julia.readthedocs.org/en/latest/manual/performance-tips/#avoid-containers-with-abstract-type-parameters it is not recommended to use parametric type Int. Changing it on my machine to Int16 speed up code from 31 sec to 1 sec. Unfortunately I am not familiar with sudoku neither with Julia to improve it better.
