Execute things on the main thread easily.

MainThreadExecutor.java

public abstract class MainThreadExecutor {

    public MainThreadExecutor() {
        MinecraftServer.getServer().processQueue.add(new Runnable() {
            @Override
            public void run() {
                call();
            }
        });
    }

    public abstract void call();

}

Can be simply replaced by BukkitRunnable.runTask()

@airidas338 I actually never thought of that, but this is a little more informative in a multi-threaded environment. Also, it might possibly be faster since it wouldn't go though the Bukkit scheduler.
