Subject: [PATCH] Windows: fix errormode

By default Windows will pop up that nasty "Send Information" dialog when
the application crashes. This will feed some information back to MS, if
the user confirms, but has no real added value. Instead, it breaks batch
processing, as that dialog requires user interactions.
Therefore disable this cruft.
