Ordering Profiles

[Brandogs]

Feature Proposal

Profiles need to be able to be reordered manually. The default profile to load should be the first in the list.

We should add sort_by field to determine the order the profiles appear and remote the default profile field.

This will require a few changes.

1. The Profile model needs a new field called order. This will be an IntegerField that is unique with the model's km_user field. We need to make sure this field is correctly populated when a new profile is created.
2. We need a serializer that takes an array of IDs and sets the order field from the data
3. We need a view that exposes the ordering serializer

Items 2 and 3 would ideally be generic solutions because we also need to apply this ordering logic to profile topics and profile items in the future.

Django has a built-in mechanism for dealing with this that might be useful.

As far as modifying the order goes, I think our best option is a PUT request to the list endpoint with an array of the profiles' primary keys in the desired order. The collections we're dealing with are small enough that it's not a pain to specify the order of the entire collection, and our traffic is low enough that I don't think concurrent requests will be a problem.

Sounds good to me
