Be able to manually do a save for realms so that backups are precise.

Backups on a Realm help us to go back to a certain point in the world. The problem is that saves happen randomly, so for example, I did something and only need to go back 2 minutes, but the most recent is 20 minutes, so that can cause problems. When being able to manually save at certain points, the player can go back to that point they need to go back to instead of going back a lot more than needed.
