I tuned the mnavy reputation system, you now earn points at just over half the
rate you did before. All prior points were tuned to compensate for the change.
Those people who would lose a level of 'arr' reputation will keep their
current level (except maybe one person) - you will still need to accumulate
the necessary number of points to go up again though.
i.e. if you had a level 5 arr, and would have dropped to a level 4 due to
point loss, you will still keep the level 5 arr, but you will not get to level
6 any faster than anyone else would have.
