Added lucky votes! You can now decide how much chance players have to receive a lucky reward. The rewards and chance can be changed within the /votesettings. Lucky votes can also be turned off in the general settings.
When a player is Lucky, ONE item from the lucky rewards inventory will be given to this player.

CHANGES:
- added comments for the usage of placeholders in the messages.yml.
- data.yml: changed "voteparty" to "vote_party", for both the items and the locations.
- messages.yml: changed "broadcast" to "vote_broadcast".
- fixed the problem when a second voteparty starts while one is happening already. Voteparties are now placed in queue when one is active.
- added default items to the lucky rewards inventory.
