Changed love.math.randomnormal([mean], stddev) to love.math.randomNormal(stddev, [mean]);

Changed love.math.randomseed(seed) to love.math.setRandomState(state) and love.math.setRandomState(low, high). Added low, high = love.math.getRandomState().

love.math.setRandomState(state) can set the random state to an integer of up to 53 bits, love.math.setRandomState(low, high) can set the random state to a 64 bit integer by using the first argument as the lower 32 bits and the second argument as the higher 32 bits.
This allows for reliable setting and saving of the state of a RNG.
