Acrobatics: cap same-location fall counter for XP gain
It used to increase boundlessly, thus preventing players from gaining XP for a while even after moving to another place.
Add diminished returns when a player has earned too much XP

When a player reaches a certain (configurable) threshold value of total
XP earned in a specific skill, his earned XP in this skill will be
decreased.

Depending on how far the player has exceeded the threshold value, his
XP will decrease more. After the (configurable) time interval of 10
minutes, the registered data will be cleared and the player can earn XP
as normal again.
Rolling xp diminishing returns

This adds on top of the diminishing returns system a mechanic such that gains will expire the configured number of minutes after they occured, rather than all being reset at once.

This prevents someone from not getting diminishing returns on the xp gain they recieved just before the reset would have occured.
