Switch random number generation to C++11 style RNG

[stephengtuggy]

C++11 style random number generation apparently produces higher-quality randomization. It would be good to use if we can, I think.

anything in the way of using mersenne twister algorithms ? they are available since C++11 , they have a high quality uniform distribution when used in combination with std::random_device (depending on the OS) but should not be use to generate cryptographic keys mt19937

this is a simple example with a uniform int distribution

#include <random>

int rand_one_to_hundred() {
                    std::random_device rd;
                    std::mt19937 gen(rd());
                    std::uniform_int_distribution<int> dist(0, 100);
                    return dist(gen);
}

@jurassicLizard yes, that is exactly the sort of thing I was thinking of. mersenne twister should be perfect for the job.

Already done in /engine/src/resource/random_utils.h
Now just need to find all the instances of rand01 and stuff like that and convert.

Oh, cool! Did not know that.
