0.2

• Added a player data API to Bukkit and Bungee
• Extended the Bukkit's Metadatable API
• Added conversion methods between Bungee's and Bukkit's ChatColor
• Added Spigot support, it inherits and improves all Bukkit's features, it also has some additional features
• Added support to Bungee's ChatComponent to BungeeCord and Spigot
• Extended the Chat API to support Array<out BaseComponent> and BaseComponent without loosing events and formatting on concatenations
• Added Plugin.register(listener), a shortcut to plugin.server.pluginManager.register(listener) and the equivalent on BungeeCord, it can take multiple listeners to register them all at the same time
• Added Plugin.unregister(listener) and Plugin.unregisterListeners() to BungeeCord

Example usage:

class MyNicePlugin : JavaPlugin() {
    companion object {
        lateinit var instance : MyNicePlugin
    }

    override fun onEnable() {
        instance = this
    }

    override fun onCommand(sender: CommandSender, command: Command, label: String, args: Array<out String>): Boolean {
        sender as? Player ?: return false
        if(command.name == "silly") {
            val data = SillyPlayerData[sender] ?: return false
            data.silly = !data.silly
            data.tellHim()
            return true
        }
        else {
            return false
        }
    }
}

class SillyPlayerData(player: OfflinePlayer) : PlayerData(player) {
    companion object : AutoDataCompanion<SillyPlayerData>(MyNicePlugin.instance, "SillyPlayer",
            SillyPlayerData::class.java, ::SillyPlayerData
    )

    var silly = false

    fun tellHim() = player?.sendMessage((if(silly) "You are silly!".red() else "You are not silly :)".green()).str())
}

• Provides Kotlin libraries in runtime for others plugins
• Allows ChatColors to concatenate, example: ChatColor.RED + ChatColor.BOLD + "Red and bold"
• Simplified color API using extension methods: "Red, bold".red().bold()+" and italic".italic()
• Any?.str() will return an empty string instead of a "null" text when the variable is null
