1. Converted `MinecraftWindows.rc` and `Resource.h` to UTF-8 from UTF-16(they didn't use any UTF-16 symbols anyway);
2. Added explicit signed->unsigned integer casts in `gdraw_d3d1x_shared.inl` for C++11 compatibility
3. Linked against `legacy_stdio_definitions.lib` to avoid undefined references to `_vsnprintf` llvm-link errors
