Pirate NPC improvements and Online Alpha bug fixes

v0.7.74
-Update to pirate npc logic to fix situations where they may not attack the player or would wait for the LOD system to tell them they could.
-Update to pirate towers pathing to fix some pathing issues with walls
-Fixed online cooking and water stations so client interaction is the same as the host and items cooking/water status is in full sync.
-Update to buried treasure in online games so they spawn treasure correctly and destroy correctly.
-Updated treasure logic for sunken treasure in online games so they have the same items found in single player.
-Fix for an online EXP bug where clients could gain exp from dead creatures.
