ADDED Permission-based exp buffs! Something like valhalla.exp.smithing.50 will give the player 50% extra smithing exp. For optimization purposes, though, the player will also need to be given valhalla.exp.smithing for this example.
valhalla.exp.all can be used for general all-skill exp buffs.
ADDED WorldGuard flag to block double jumping
ADDED Tridents may now be configured to deal extra damage with the Impaling enchantment, so it now basically acts more as a Sharpness enchantment for tridents. They can be configured to only work in wet conditions, and they can add different damage values when used melee or ranged
ADDED Perk reward that toggles flight for the player

FIXED Default configuration values being forced, even if removed from a config
FIXED Custom damage sources nullifying immunity frames on the affected target
FIXED Custom damage sources from hits having damage multipliers apply twice, causing it to be weaker than intended in the early game and stronger than intended in the late game
FIXED Shields not getting lowered as a result of the "shield disarming" stat proccing
FIXED Custom potion effect indicators not re-appearing when logging off and back in
FIXED Stuns not affecting players

ATTEMPTED FIX At a ConcurrentModificationException during mining with the custom mining system enabled

TWEAK Party exp sharing no longer fires EXP events for every player, which should help with performance
