It's the little things

First beta of ITLT v3 for MC 1.21.1.

• Completely rewritten from the ground-up
• Support for Forge and Fabric
• Simplified config
• Modpack info shows in crash reports
• Warns when on wrong GPU (e.g. using integrated graphics when dedicated is available)
• Now works on dedicated servers as well
• Update checker

Known issues (all platforms):

• Only one PNG icon is currently supported. No ICO/ICNS support yet, no multiple PNGs for different icon sizes.
• Custom window title doesn't work yet
• User guides are missing
• The warnings currently show a hardcoded short message like "Too much memory" or "Outdated Java", will be improved in a future beta
• Welcome screen feature is missing
• Preloaded servers feature is missing

Known issues (Forge):

• The filename of the built file is a different format than the Fabric version

Known issues (Fabric):

• Modpack info does not show in crash reports on Fabric yet, due to missing APIs.
  • Need to hack into Minecraft internals and implement it myself, which takes time to figure out. Meanwhile Forge has a simple one-liner API I can use
• Warnings only log to the console and no GUI is shown on Fabric, due to missing APIs.
  • Forge has an API for this, Fabric needs me to implement it myself, and I haven't made a GUI for Fabric yet, so console logs only for now
• Warnings and explicit GC may be broken on Fabric if you replace the title screen with another mod.
  • Fabric lacks an API for checking when the game has finished loading, so I currently have to rely on checking if the title screen is shown instead
• The ITLT update checker doesn't work on Fabric yet, due to missing APIs.
  • Will look for another library mod for this in a future beta

Required library mods (Forge):

• Nothing... everything I need is included in Forge

Required library mods (Fabric):

• Fabric API (separate from Fabric Loader)
• Forge Config API Port
