[BUILDER] Create a hub for worlds

[FurrehIzzy]

A spawn with a portal hub needs to be created. The portal hub needs to have the following:

1. Portals to the player worlds
2. Portals to admin worlds, such as flatlands
3. Portals to streamer world
4. A spawn where first timers spawn
5. A rules section

There may be more that needs to be created, but we'll follow-up with that as time goes on and needs present themselves.

• Portals need to have permission group restrictions.
• a chat notification for players if they try to access a portal to a world they don't have permission to access.
• a eula accept function when entering certain worlds. This will list basic rules for each world and they must accept before they are able to do anything within the world. For example, Griefing, or when entering a world that's meant for kids to play. Etc.
