Setup.exe update

[Robert Collins]

Hi folk,
	A new release of setup.exe has been made. As usual it's
accessible at http://www.cygwin.com/setup.exe.

It includes the following key new features:
* New GUI that should be less prone to 'disappearing'.
* Can download from multiple mirrors - use CTRL-Click or Shift-Click in
the mirror site dialog.
* Updated chooser that allows full installs with ease, as well as source
only installs of packages.

as well as numerous bug-fixes and under-the-hood improvements.

Thanks go out to all the contributors to this version, which includes
