Win32Pad 1.1.2

Here is a quick release I put together to fix a few things reported by users.
From Changelog:
+ Add .txt extension during Save As if the filename doesn't have any extensions
x Fixed the file format detection code (seems I broke it in 1.1.1).
x Fixed up the Setup Script. (Let me know of any problems)

P.S. Enjoy.
