MultiVoteListener

Added per service message

You can now add a service specific message issued to the user upon vote. It replaces the globally defined reward messages (player_*_reward) in the messages section. Just add the following line in a service section:

usermessage: 'Some text to send to the user'

Fixed a minor issue when new users vote

Sometimes votes of users who joined for the first time where not recognized as known users due to the nature of the Bukkit's hasPlayedBefore() method.

Fix empty text messages

If a user message is left empty in the config it will be suppressed.
