Add spectator slots for the player's cursor item and crafting slots
Added:
/invsee now shows the item that the target players is holding on his cursor
/invsee now shows contents of 'personal' inventories such as the player's crafting slots, workbench slots, anvils, smithing tables, enchanting tables, stone cutters, grindstones, and looms
Fixed:
A bug that caused some tasks to execute on the server thread instead of an async worker thread
Tabcompletion could sometimes yield duplicate players
