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, and force an update check on next launch
• 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
  • Add new error for when game has been installed from Steam, but wrong game was launched from Steam (closes Mod packages may be installed to wrong DataDir on Steam #26)
  • 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
  • Replace path.info with support,info, shows more info
  • 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
• When updates are blocked, warn user and prompt them to re-enable updates in the following cases:
  • The first time LK is launched (if updates are blocked before first launch)
  • Every 30 days
  • After a failed attempt to install a mod that requires newer LK or ModAPI DLLs version

LGTM, code wise it all seems fine, I've also tested it briefly and it still works fine on my end.

If users have issues then those can be quickly fixed anyway so I'm not too worried about merging it as-is.
