Added configuration file and a *lot* of additional logging to help track down issues with the Epic Games version of the game.

WARNING: There may be some performance hiccups from the logging, in particular when getting a loot crate check. This hopefully shouldn't affect gameplay too much, and will be gone in a future update when we don't need all of this logging anymore.

1. Added configuration file for the client mod to save some settings outside of the game.
   
2. The configuration file is located at
   `%APPDATA%/configs/RampagingHippy-Archipelago/ap_config.json`.
   
3. The last used server, player name, and password are now all saved to the configuration
   file when successfully connecting to a server, and are loaded from the file when
   opening the game.
   
4. The mod now logs a lot more detail around sending and receiving checks, to help debug
   issues with checks not sending.

Fix Brotato crashing when using the mod in some cases on the 1.1.8.0+ releases.

• Fixed the game crashing when starting a run if the player receives enough XP from the multiworld to level up.
  
  • This seems to be related to Brotato updating to Godot 3.6 with the 1.1.8.0 release.
