This update adds some more functionality in the config.yml file. Although it is unlikely to break anything, it is a good idea to make a backup of your config files before updating to newer versions.

New:

• You can now add 'random: true' to your reward groups to randomly select one reward command from its group when claimed. See example usage here.
  
• Added sound, volume, and pitch options for opening the reward menu.

Changes / Fixes:

• Config options are now validated on startup. This means that if you are missing new config options when updating the plugin, it should automatically add the missing options.
