Infinite Dimensions

Create train integration:

• Now works on Forge.
• Is hooked up to the syncing of portals.
• When changing a dimension of a portal with rails through it, the game automatically tries to update the rails' destination (and breaks them if it can't).

Tweaks:

• You can now use creative mode pickblock on infinity portal blocks, giving you the respective key.
• Config options now include ways to set a cap for dimension scale and tweak the length of/disable iridescence side effects (initial phase, cooldown).
• There are now chat error messages for when an infinity portal fails to teleport the player for any reason, intended or unintended.

Bugfixes:

• Fixed a fish-related forge crash.
• Fixed incorrect teleportations with portals to deleted dimensions and all the calls to teleport the player to their respawn point.
• Fixed the "invalid player data" message when logging in to a deleted dimension.
• Fixed infinity portals not loading the other side with a chunk ticket when a non-player entity goes through (meaning they now can be used for chunkloaders).
• Iridescence-related shaders now should behave properly when the effect is applied, removed, or the player changes dimension.
• Shaders in general should be more stable (dimension-dependent ones failed to apply before until a resourcepack reload).
• There was an edge case before in which portals didn't resync correctly; this is fixed.
