Add a tool to switch the Windows display scale between 100% and 200%

81-Toggle-Scale.ps1 writes LogPixels, Win8DpiScaling and AppliedDPI for
the current user; the change needs a restart, so the .bat launcher offers
to restart at the end. It is picked up by the existing NN-*.bat/.ps1
globs and copied to Desktop\Tools.
