Feature/boolean voting

[AlvaroRodriguezGarcia-hue]

This Pull Request aims to add a boolean type to questions, i.e. questions with simple "yes" and "no" options. It also includes unit tests. It might be necessary to migrate before running the application.

Unlike other question types, this one creates its options automatically upon creating it with no options and doesn't allow any other options. This will be indicated in a BadRequest error when trying to add them.

This type is also compatible with blank voting, creating a third "blank vote" option in that case.

I do not find the feature to be fully ready yet. Apart from the comments and suggestions I left, I also would like to remind you that for this feature to be considered complete it must handle a vote coming through store/views.py > post, which is the function responsible for registering users votes. I do not see that either

On another note, I would prefer if you guys followed the issue management corrently, I do not see any feature issue associated to this PR, but I saw 2 bug issues corresponding to problems found while working on this that only apply to your branch because it has to with how YOUR implemented feature does not integrate correctly other features. Those are not bugs, they are problems within your feature and should be discussed in the feature issue or in this PR if those problems are found by a reviewer. Please take note for the next time.

Now the issue of handling a vote in store > views.py should be solved. Please review the code again when you can.

Okay I now understand the particularities of the tests, I still don't like the way the question options are handled in the admin page but that can be dealt with at a later point.

Anyways, good job!

The tests run correctly and the functionality works. Good job!
