Added 'make_kodi_home_symlinks.bat' script for creating symbolic links in the build directory to files and directories that Kodi expects to find in KODI_HOME. This allows Kodi to be run from the build directory without KODI_HOME having been explicitly set.
Fixed a few flaws in make_kodi_home_symlinks.bat:
Rogue ENDLOCAL at the end was turning off delayed expansion
Missed Win32BuildSetup\Dependencies
Don't need to symlink contents of 'system', as we're linking the whole dir
Fixed some flaws in make_kodi_home_symlinks.bat: only need the Win32BuildSetup DLLs, missing 'media' directory
