    Default Pseudo-random number generation

    What does Novashell use internally? Lua's math.random() isn't very good (it uses C's rand() function) so if Novashell uses something different internally, perhaps you should expose it.

    Also, misc_util's definition of random/Random can be simplified. It unnecessarily tests whether the arguments are nil, but since functions are first class values you can do:

    Random = math.random
    random = Random

    Thanks, will fix.

    About random:

    Right now I'm using lua's random only. I have a random class based on the mersenne twister algo I should probably plug in at some point, as an object, so people can have multiple custom seeded reproducable (on all platforms hopefully..) number streams.
