add NUL on Windows Fundamentals for Legacy PCs (WinFLP)

WinFLP don't come with NUL device as default
so some directs don't work
like
dir abc 2> nul
and error message is not suppressed

re-enable it, following the tips on
http://www.cynosurex.com/Forums/DisplayComments.php?file=Batch/NUL_Missing_on_WinFLP

prepare 2 files from XP CD and copy them to system32 folder
\WINDOWS\system32\drivers\null.sys
\WINDOWS\system32\regini.exe

download the Null.reg, Install.bat
