core-cpan-diff: various enhancements

* Extracted directories are cached and re-used
* Perl vs CPAN version mismatches shown in summary output
* Various minor code cleanup

Some diagnostic output was surpressed in diff mode, but not all.
I found the output confusing to follow in diff mode as a result
so I enabled some of the previously surpressed output.
