"Wubba Lubba dub-dub!" - Rick Sanchez

Adds a Rick and Morty inspired portal gun for NeoForge 1.21.1.
Right click to tear open a portal. Step through and you come out somewhere else entirely.
Destinations are drawn from every dimension the server has loaded, so anything added by another mod is fair game. Safe spots are found using each dimension's own terrain generator, which means it works with dimensions this mod has never heard of.
Install Immersive Portals, and you walk through smoothly instead of being teleported. Portals stay opaque either way, you can't see where you're going until you're through. Entirely optional.
Portal lifetime, range, cooldowns, how far destinations are searched, and a block blacklist for surfaces the portal should never land on.
Currently everything is Creative-Mode only, until future updates.
