David James 6ceddf089f Update cros_changelog to support sort-by-date option.
Other changes:
  1. Clean up revision handling to be more forgiving if people want to use
     things that don't start with "cros/". Instead, we only enforce that
     people use tags if they want to use the one-argument version of
     cros_changelog.
  2. Tags are quoted in the command-line so that people can, for instance,
     diff 'cros/master{2 days ago}' vs 'cros/master{1 day ago}'.

BUG=chromium-os:8205
TEST=Ran ( ./cros_changelog 0.9.104.0 cros/master > /tmp/test1.html &&
          ./cros_changelog --sort-by-date 0.9.104.0 cros/master > /tmp/test2.html )
    Both commands print changes between 0.9.104.0 and master, but the second command prints results sorted by date.
