Merge PR # (Allow upcase logfile name in download_data.py)

This merge brings PR # (Bug fix: allow uppercase log filename
in download_data.py, by @ihough) into the GEOS-Chem
"no-diff-to-benchmark" development stream.

This PR adds a fix so that dry-run log file names that are
fed to the download_data.py script can have mixed case.
Merge conflicts in CHANGELOG.md have also been resolved.
