The Witness: v4 Content Update (#1338)

## New Features:

- EP Shuffle (Individual or Obelisk Sides, with varying difficulty levels)
- Ability to play without Puzzle Randomization (I.e. vanilla + AP layer)
- Pet the Dog to get a Puzzle Skip :) (No, really.)

## Changes:

- Starting inventory behavior improved (Consider starting items like doors and lasers logically even if they aren't part of the mode)
- Audio Log hint system improved (On low hint counts, you will no longer get the same locations hinted every time, i.e. always hints are shuffled)

## Fixes:

- Many fixes to symbol requirements
- Fixes to "shuffle_postgame" (What checks are evaluated as "postgame" in specific modes)
- Logically irrelevant doors are now "useful" instead of "progression"
