New discussion flow without topics

[ddfridley]

To simplify things for users since they are not familiar with this, and to simplify things for ourselves technically, we want to eliminate the process steps that involve Topics, and focus only on questions.

1. Provide 2 Questions
2. View questions from 9 others
3. Group similar questions
4. Choose the most important 2 questions.

There is a branch I started https://github.com/EnCiv/unpoll/tree/simplifiedq that makes a variation of the "Ask" story that just asks for 2 questions (and not topics).

Start by checkout/pull that branch and work in there.

We need to modify the rest of the discussion around just doing 2 questions - you can do this in the "Unpoll" story.

Then I think we need to make some changes to the apis to support questions only.
