Added: Ability to change the name of the item displayed under %item%. (Suggested by @luffy1025 )
Added: A "Cooldown" option under Config.yml to let you set a cooldown before players get checked for captchas again after they have completed a captcha successfully. (Suggested by @luffy1025 )
Changed: Renamed the file config.yml to Config.yml. Just backup and delete your old config file, and let the plugin regenerate it for you.
Changed: The Items.yml file. Please let the plugin regenerate it for you.

Since the ability to decide what goes into the %items% placeholder allows you to use any language you want, if anyone translates the file to other languages and would like to share your translated file, please PM me a pastebin of your Items.yml file and I'll put it in the next update as a locale file
