Update dependencies to more recent version

All these version ranges include the latest version at the time of this
commit, except for the selenium webdriver.  There version 3 is incompatible
with version 2, and switching to a version 3 library appears to require
switching to version 3 docker images as well, which would entail using
different browser versions which in turn would lead to differences for a
large number of screenshots.  That doesn't appear warranted at this time.
