Vote Party type Locked Crates improved + bugfixes and improvements

• Vote Party type "Locked Crates" behavior has changed: crates now drop like anvil's until they hit the ground.
  Because of this change, "Locked Crates" better suits a Vote Party setup where the chests are floating + it becomes more fun!
• Vote Party type "Locked Crates" and "Pig Hunt" can now be stopped with /voteparty stop.
• Vote Party type "Pig Hunt" has new default settings. (health and damage)
• Fixed playernames not changing after performing a Mojang name change.
• When setting a Vote Party location, the /votesettings no longer automatically closes to allow bulk editing.
