Handle inventory max stack sizes better. Fixes BUKKIT-5564

Quellcode durchsuchen 
Make sure we check the inventory's max stack size where appropriate and
don't assume the inventory slot is able to take our entire stack just
because it is empty. We also ensure the client is updated with the correct
slot contents and cursor contents in cases where the max stack changes
result in different behavior than the client expected.
