 Fix bug 254, sort of: make the default NT service user NetworkService rather than NULL (system).  Also, add a --user argument to --service install so that admins can override this default: this latter point should take care of most of my objections to NetworkService.  I have no idea whether this even compiles.

+  o Major bugfixes (NT services):
+    - Install as NT_AUTHORITY\NetworkService rather than as SYSTEM; add a
+      command-line flag so that admins can override the default by saying
+      "tor --service install --user "SomeUser"".  This will not effect

   o Major bugfixes (other):
     - Fix a crash bug in the presence of DNS hijacking (reported by Andrew
       Del Vecchio).
