[patch] setup.exe changes for Redownload/Reinstall Current version or Sources only - Part 1

[Brian Keener]

Here is the patch I promised to allow setup.exe to download only sources when needed and to 
allow for the Redownloading or Reinstalling of the current version.

This is part 1 (ChangeLog Entry) - Part 2 will follow with the actual diff.
