[Catalog-sig] Case sensitivity of package names

I think the way setuptools currently works is this:

Every name gets converted to its lower-case safe-name equivalent.
All dependencies, file names, resource identifications etc
are based on that version of the name, *not* the "true"
name of the package.

Then, when setuptools tries to find a package whose "true"
name is in mixed-case, it uses the lower-cased safe-named
version, and PyPI reports that the package does not exist.
Then, setuptools queries the entire package list, trying
to find out the original spelling of the package.

I'm sure Phillip will correct me if I'm wrong.

See above - I believe setuptools package names are case insensitive
today.
