Turn on autocomplete for DOS shell

You can enable filename completion in the NT "DOS" shell by editing
HKEY_CURRENT_USER\Software\Microsoft\Command Processor
and changing the CompletionChar value to 0x00000009

9 = tab for those that don't know. The feature works almost the same as in *nix shells (bash f.ex), but now as good

It's a nice thing if you ever do anything in the shell.
