    Revert "Seed the M_Random random number generator from the system time to give"

    This reverts commit 59aad53bbde97e75e06717ea1b49bd3c92941b83.

    Closes #665.

    The original commit enhanced the behaviour of Doom to make some of the
    pseudo-random behaviour less predictable. Whilst this is a nice feature, it's a
    feature that vanilla lacks: replaying a demo would result in those behaviours
    (wipe, pitched sound effects) being identical each time. This is not the case
    with the above feature.

    It could actually be quite useful to ensure that such behaviours are
    reproducible to fine-tune our emulation of e.g. Doom/Heretic/Hexen pitch
    shifting. Perhaps in the future our testing will be enhanced to compare
    multimedia output of Vanilla versus chocolate for demo playback, in which case
    we would also need to have reproducibility here.
