0.0.18 - Still Xen, but the Remake this time

Minor feature and bugfix release to address some more issues with egl-sync and add some smaller QoL features.

Changes:

• auth command
  • --import will now work on Linux (WINE prefix will need to be specified)
• egl-sync command
  • Added --disable-sync to disable automatic sync without unlinking
• launch command
  • --set-defaults/--reset-defaults to save specified parameters (--wine, --offline, etc.) to the config
    • Can be used with --dry-run to quickly change a setting without manually editing the config or launching the game
    • Does not save environment variables, those still have to be added manually to the config if required
  • wine_prefix config option (will behave like --wine-prefix)
• list-installed command
  • Added --show-dirs to print installation directories for games in list

Other Fixes/Improvements:

• Log will show a warning if -y was used incorrectly
• Updates to User-Agents used to the latest EGL version
• Fixes --egl-wine-prefix and --egl-manifest-path for egl-sync
• Fixes --yes/-y for egl-sync
• Epic Games Launcher synchronisation will now correctly resolve WINE dos device mappings
• Uninstalling games will now work correctly if automatic sync is disabled
• Manifest serialization now fully supports the same features as the Epic Games Launcher, including JSON saving JSON manifests in the newer binary format
  • This isn't currently used, but might be utilized in the future to reduce manifest storage requirements and loading times when dealing with games that use the older JSON manifests such as Fortnite
