Remove minwindef include; docs and whitespace cleanup

Remove an unnecessary #include <minwindef.h> from pkgread/typestrans.h and perform minor whitespace cleanups in desktopini/main.cpp and pkgread/dllmain.cpp. Update notes/symlinks.md to explain that appxinfo.h and main.cpp now use #include "../<ProjectName>/<ProjectName>.h", so the previous symbolic links are no longer required. These are non-functional cleanup and documentation updates.
