Autorun.inf not correctly identified from 'file' command.

[Socratis]

Based on a ​recent discussion in the forums, the contents of the "Autorun.inf" file used in the GAs Windows installer, could/should be slightly modified to bring it in "compliance" with the 'file' command found in almost all Unix-based OSes.

The problem arises from the fact that a proper "Autorun.inf" file should start with the "[autorun]" text. The current "Autorun.inf" file starts with the license (a comment). If the "[autorun]" entry gets moved at the beginning of the file, before the comment, everyone/everything is happy.

Patch is published under the terms of the MIT license. Both lines ;) :
