- Merged in Microsoft's Unreal Build Tool changes for VS 2015 support, and Universal App Platform support
- VS 2015 support is disabled by default (the engine is not yet compiling with VS 2015)
- Use the new '-2015' option when generating project files to enable VS 2015 support
- Windows SDK 8.1 is used by default. To use Windows SDK 10, enable WindowsPlatform.bUseWindowsSDK10
- UAP support is disabled (not supported yet, work in progress.) Use WinUAPPlatform.bEnableUAPSupport to enable it.
- Various loose ends still remain (search for "@todo UAP" in Unreal Build Tool code)
