12/21: Combat tweak- made fatigue rolls more difficult by removing 2 free keep dice that were added to the roll. Now just ensures that the minimum dice rolled is 2 for those with very low dice pools.

Added maximum number of posts to boards, calling the oldest to fall off when the newest is posted.

XP bonus by age: Although aging isn't yet in, I decided to go ahead and add the initial xp award for age and retroactively added it to existing characters. The scale is as follows:
bonus = (age - 15)/4
if age > 20:
bonus += (age - 20)
if age > 30:
bonus += (age - 30)
if age > 40:
bonus += (age - 40)
if age > 50:
bonus += (age - 50)
if age > 60:
bonus += (age - 60)
