AD Stats

New:
- Skill milestones now grant real gameplay bonuses, not just achievements:
Mining/Excavation/Foraging/Farming/Fishing give a chance of extra resources when gathering;
Fighting/Archery give a chance of bonus damage (including in PvP by default);
Defense gives a chance of reduced damage taken;
Alchemy gives a chance of longer-lasting potion effects, including on splash potions thrown at others;
Enchanting gives a chance of a cheaper cost.
- All of the above is configurable per bonus category on the server.

Fixed
- Combining enchanted books at an anvil wasn't being tracked toward the Enchanting skill (only the final application to a tool/weapon counted) — every combine step now counts correctly.
