Multithreaded Preloading of Data

[DrZed]

• What is the purpose of the pull request?

  • To improve Save Loading speed (up to 440% faster)
  • To improve New Game speed (up to 104% faster)

• Give a brief description of what you changed or added.

  • Added DocBuilders.java
    • Replaces the Document Builder in Main with a dedicated cluster
    • This was required to make threading work, as JAXP is not thread-safe
  • Added PreInitializationThread.java
    • This is called fairly early in the stack, before the window is requested to even draw
    • Doing this allows things such as BodyCoverings, Race, ETC to be already prepared when needed
  • Added NPCRegistry.java
    • This moves NPC's from Game.java and makes it easier to see/sort/modify them
    • Split Relationship Registration to it's own function below the NPC Initialization
  • Added NPCThread.java
    • This allows NPC's to be initialized in clusters on separate threads

• Are any new graphical assets required?

  • Not at all

• Has this change been tested? If so, mention the version number that the test was based on.

  • This change has been tested and proven for 4 years in my own build mod.
  • It has finally been fully vetted as stable, by roughly 5-11k users varies by version number.

• So we have a better idea of who you are, what is your Discord Handle?

  • @keldonslayer

• If you want quick feedback, you can use @Innoxia, or jump on the Lilith's Throne discord and send Innoxia a PM.
  Done did.

I can split these 2 commits into separate PR's if wanted, however both depend on DocBuilders due to the nature of JAXP.
