setup: bump all upper pip dependency versions to minor updates of what currently is available and testable on pypi

Based on manual editing after:
pip freeze | sed -n 's/==/ /gp' | while read p v; do  sed -i -e "/\<$p[ \"]/s/\(\",\|$\)/, < $v\1/gi" setup.py dev_requirements.txt; done

These updates have been tested with automated tests and some amount of manual
testing. Remaining problems will hopefully be caught by additional testing
before the branch is declared stable.
