Infusion dev numbering proposal

Hi, Justin:

I will wait for others to way in further on the branching strategy, but I
wanted to respond to this point:

Deleting dev releases is a bad practice, and much more trouble than
confusing semver ordering.  Builds that rely on the version would break on
the next commit or test run, for starters.  Package authors would have to
update before they can resume even testing their own work.  This kind of
unplanned disruption can cause chaos even if you're just talking about the
handful of people who use dev builds within our community.  It's better to
warn everyone and move forward than to potentially and confusingly break
work in progress.  Even npm themselves strongly discourage unpublishing
versions <> in the documentation for
the command used to do so.

I can see a lot of other strategies here that would accomplish the major
goal (avoiding confusion between pre and post release), for example,
flagging the pre-2.0 releases as deprecated (which is what npm suggests).
