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
The Debug|x64 and Release|x64 configurations had no PostBuildEvent to
deploy sound assets alongside the executable. At runtime, SoundEngine
looks for Durango\Sound\Minecraft.msscmp and music\ relative to the
output directory, causing silent failure (no sound effects or music).
Add post-build xcopy steps for both configurations to mirror what the
Durango build already does.
