[Survival Update]: Disable spawning on certain planets & Naming planets

Greetings!

As the topic suggest this is about the new spawning system, which overall i feel is much smoother than before!

However as soon as the update hits i am going to setup a world for me and my friends. We will be using several planets and moons (both vanilla and mod sourced worlds).

A problem I ran into in the current state of the beta is that right now you can literally spawn on ANY world, be it a planet or moon.

I would like to see an option to disable spawning on the planets you don't want anyone to spawn on (Example: cant spawn on any planets with 2+ g, or sub 0.7g)

But also with this in mind, what would also help as an alternative:

I would love to see the option when you have created a planet to name them manually as an alternative.

So when you re-spawn you don't see like two or three different "EarthLike20e945a204y50275". Having no idea which one is which.

Having the option to name planets, especially in the case above. Naming them into different things helps identifying everything in the entity list. Thus this would go a long way in making sure people can spawn where they are supposed to :).

I hope this is not to complicated to implement.
