Move form validation and saving of instances
to the form class. From here you are able to instantly
save your validated form to the database. Further
reduces the size of the views.
Form may need error handling on not having
found a Contributor before saving the form instance.

Lost order argument in query for CommentarySearchForm
results in the last commit.

Reduce the amount of logic in the `commentaries` and
`browse` views methods in the `Commentaries` app. Further,
added a return method to the `CommentarySearchForm` to help thin
out code in the view.

Implemented basic modelmanager on Commentary
model. Created `vetted` and `awaiting_vetting` methods
and ipmlemented to few view methods.

Commentary model inherits from TimeStampedModel now. It
also includes migrations related to the inheritance:
 - Add added field on Commentary
 - Alter field last_activity on Commentary

The core model is extended with an abstract model called
TimeStampedModel. Future and existing models should
inherit from this model to include the default timestamp fields.

- Alter field in_agreement on comment
- Alter field in_disagreement on comment
- Alter field in_notsure on comment
- Alter field is_cor on comment

I've opted for hanging indentation

foo = long_function_name(
    var_one, var_two,
    var_three, var_four)

instead of aligning with opening delimiter

foo = long_function_name(var_one, var_two,
                         var_three, var_four)

because the former makes more sense to me. See

First pull request :-)

Really, don’t!

Instead use something like ReadTheDocs to automatically render & host on every push.
