- Added a top-level .xcconfig file to Xcode workspace for use with UnrealGame/etc so it knows where to find staged data, and set the commandline automatically
- Stage the UECommandLine.txt file for modern builds because we no longer make the Bootstrap .app
- Added XcodeBuildMode enum/string so scripts can tell when the project is being built (so build time could act differently than stage time, etc)
- Making use of the enum and other env vars to skip steps when not needed
- Other fixes for project generation
- Added -modernxcode and -legacyxcode comandline options which will override the .ini setting (refactored all UseModern checks into one function)
- Support for programs that have a .uproject, and GPF with -game -project=<program.uproject>
- Added success return value to FinalizeAppWithModernXcode
- Added quotes to fix paths with spaces in GenerateProjectFiles.command
- Enabled parallel AddAdditionalNativeTargetInformation for gathering Frameworks from targts, now that parallel project generation has been enabled and most parallel issues are fixed
