Remove bad server.scheduleOnMain disconnect calls from old patches
The new behavior of disconnect to block the current thread until the disconnect succeeded is better than throwing it off to happen at some point

Subject: [PATCH] Fix inconsistencies in dispense events regarding stack size
The javadocs for BlockDispenseEvent suggest the ItemStack is a single
item which is being dispensed. Before this fix, sometimes it was the whole
stack before a single item had been taken. This fixes that so the stack size
is always 1.
