check for Python 3.2

remove inappropriate wheel tag override

I misunderstood how these tags are interpreted.
We do not want `py2` and `py3`, we want `py27` and `py33`,
which indicate >= matching in the minor version.

check explicitly for 'dev' before adding the note to docs

allows 'maint' suffix (or similar) for the maintenance branches,
so they don't get the note on every page.
