(re)create miniconf proposals

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

Add release materials check boxes to miniconf proposal

We need to have people who are submitting a miniconf proposal agree to
releasing the material. The easiest way to do this is to just make it a
proposal like the other two types. We don't have audience type for
miniconf, instead of deleting it just have a default - it's easier.

WARNING: This requires a real migration to be performed before use.

Remove AceEditor

I cannot find the benifit to this over the base editor.

Tabs work, but that's pretty minimal. And tabs don't work on GitLab or
GitHub, so I don't feel not having that is substantual to functionality.

Add ' *' required markers back

The bootstrap renderer did not do anything to signify required rows. We
can do this by adding a class for CSS to work on, and add this field in
a more simplified manner.

label-required == append ' *'

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.
