This is a fairly huge update:

If you encountered messages like `Skipping Entity with id` read the beeFix Notice in our wiki.

You may delete your locale file to avoid wrong locales.

I removed the flying creeper since this was a buggy mess. I added the ghost creeper as a replacement.

You can now also choose between 3 new night selection types. And use the player placeholder in end and start commands.

Thanks to Darkmage4 for the bug report of the bees, which lead me on the right track
Thanks to RedBoard and @frank42 for the suggestions.
Thanks to @XiaoMoMi for the Chinese locale
