Post Office

• Added post box (barrel and sign) protection. Easily disabled in the config if using your own.
• Prevent players from swapping cursor items out of a post box.
• Prevent players from dropping items out of a post box.
• Prevent players from condensing items out of a post box.
• Add a 10 second delay to the "You have mail" notification when connecting.
• Added a plugin update notification system.
• Added extra language translation options to the config file.
• Removed the barrelname command as this should only be set once. Edit the config directly and use /postoffice reload to update the barrel name.

Post Office has now been added to GitHub as a GPL3.0 Open Source project. You can find it here: https://github.com/shantek/PostOffice

• Coming soon, v2 will update the plugin to use a players UUID and add additional flexibility to the plugin.
