Better error handling

[Kade-N]

• Clean up various areas of code, less spaghetti
• Mod Identity
  • Relocated dllsBuild handling to Easy Installer (it's not relevant anywhere else)
  • Reject installing mods where dllsBuild is present but cannot be parsed as a version, with a clear error message
  • When installing a mod that requires newer DLLs version, show current and required DLLs version
• Spore Path handling (closes Change Galactic Adventures Not Found message #13)
  • Overhaul how LK locates the game's folders
    • New behavior attempts to mimic how the game itself does it, by only checking for DataDir
    • Idea is that if the game can run, then LK should work, and contrapositively, if the game cannot run, LK should not work
  • Removed PathDialog, users can no longer choose the game folder
    • Users often chose the wrong one, leading to problems
    • Should be obsolete - if the folder can't be detected, then the game likely won't work on its own
    • Also removed LauncherSettings as this was the only thing there
  • Add new error for when game has been downloaded from Steam, but Steam still needs to run its installation script
  • Clean up code relating to registry paths, add support for C&C path on GOG/Steam (unused, but may be useful in the future if we implement C&C Fixer #21)
• Centralize and update how errors and support info is displayed
  • Added SupportInfo which standardizes how this info (game version, LK version, paths...) is obtained and displayed
  • Most error messages now use this system
  • Updated phrasing in many messages for consistency and clarity
  • Added checks for LAA/4GB patch, if enabled then this is displayed with game version
  • Added new warning when LAA/4GB patch is used on an incompatible game version (currently just Steam October2024 due to steamstub DRM)
  • Easy Uninstaller now shows game version info
