(re)create miniconf proposals

This is a partial revert of 6d864e8ce56b8cbb53c90c620729238181c6c8ae
- plucking out the bits we want to re-use

Use full imports not .

And tox to py3.6

Use a selectbox for of_legal_age

To me, this registeres to a user as a required field better than a
radio-button.

As well, we now signal it as "required = True"

Cleanout conf-specific proposals.

We don't have these mini-confs (yet).
We don't want these files.
We're not going to rename the release in 0010 and drop all the extra
tables in 0011, we're going to toss them on the cutting room floor and
call it good.

They're in git, we can look at this commit and past ones on how to
recreate these for new proposal additions going forward.

Mass style-check update

Seems okay.
