Legends' Quest: Various polish & fixes (#1275)

* ObjectStep feat: add `copy()` function

* ObjectStep refactor: Reformat code

* Legends' Quest refactor: Reformat code

* Legends' Quest: Add teleport step to start the quest

Not as a requirement, just as a text hint

* Legends' Quest: Remove Bullroarer as a requirement for the "Mapping Kharazi" category

The Bullroarer is received at the beginning of the "Contacting the locals" category

* Legends' Quest: Change the Item requirement for the "Mapping Kharazi" step to be any notes

The notes will only be filled in during this step

* Legends' Quest: Add tele hint for getting to the Jungle

* Legends' Quest: Add a worldpoint to the "enter the jungle" step

This makes it more clear where you should go, and lets people check the map to see what teleport fits best for them

* Legends' Quest: Add a hint that people should bring everything from the section's item requirements now to avoid
rebanking

* Legends' Quest: Make the sketch steps conditional

This means the notes would only prompt to be clicked (highlighted) when you're actually in the right area

I only tested this with the east step, as I had already completed the west & middle steps when I implemented this

* Legends' Quest fix: Change "Bull roarer" to "Bullroarer" to match in-game name

* Legends' Quest: Advice bringing multiple gold bars

For most anvils, not a problem, but if you choose an anvil far away from a bank for some reason this could be nice

* Legends' Quest fix: Fix dialog step text when talking to Gujuo about what's happened to the pool

* Legends' Quest fix: Fix order of "make bravery potion" & return to jungle steps

* Legends' Quest: Add object markers to the boulders in the cave

Also refactor this step to make sure the step is the same for all the times it's entered

* Legends' Quest refactor: Deduplicate "search marked wall" step

Requires the ObjectStep changes for copy to work

* Legends' Quest refactor: Deduplicate bookcase & cave door 1 opening

* Legends' Quest fix: Add missing dialog step when climbing down the winch

* Legends' Quest: Add some TODO's for future adventurers

* Legends' Quest fix: Add missing step in the Kill panel section

It was set as the step, but because it wasn't in the panel section, no panel section was expanded.

* Legends' Quest: Clarify that you are allowed to teleport out after restoring the pool

* Legends' Quest: Add teleport hint for returning to the Legends' Guild

* Legends' Quest: More gentle hints for how to enter the jungle

* review: Fix `enterGate2HolyForce/ToSource` comment

* review: Add contextual bank hints for the tele to legends guild

* review: Add bank hint for teleporting back to the jungle
