Small Patch for setup.exe

[Franklin]

Here is a very small patch that I find helpful and thought I'd share. It
adds a button on the package selection page that "switches" all of the
possible packages. In practice this usually means that it will change from
the current package to "Skip", but if you have a local package directory
with multiple versions of a package it will switch to a different version;
you can skip those packages manually. My original intention was to add a
"Skip All" button but it looks like this would be much harder as
setup.exe is agnostic about such things.

P.S. If this patch is useful enough get included, do I need to send in a
rights-assignment form?
