love.math.setRandomSeed / RandomGenerator:setSeed now hashes the seed value before using it, which gives a much better distribution when comparing the results of different but similar seeds.
...
Cleaned up RandomGenerator:setState/getState, now that love is using the C++11 standard library.

Reverted commit 14ca947 (love.math.setRandomSeed internally calling random() a few times.) The change can break existing 0.9.x games so it will be pushed back to the minor branch.

Improved error message when love.math.setRandomSeed(0) is attempted (resolves issue #876 )

love.math.setRandomSeed now calls random() a couple times internally, to make similar seeds give less similar results when random() is called for the first time after setRandomSeed.

Added RandomGenerator:getState and RandomGenerator:setState (resolves issue #831.)
...
getState returns an implementation-dependent string representing the current state of the RandomGenerator's PRNG. setState sets the PRNG's state to an implementation-dependent string.

Renamed love.math.g/setRandomState and rng:g/setState to love.math.g/setRandomSeed and rng:g/setSeed.
...
getRandomSeed now always returns the previously set random seed instead of the current (implementation-dependent) random state.

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.
