[DRAFT] Proposal reviewing mechanisms

[sheenarbw]

This is a work in progress. If anyone wants to poke around please go ahead.

Basically how it works is:

• Users can be marked as reviewers with the is_reviewer flag
• Reviewers get access to a review dashboard where they can see proposals that need to be reviewed. It would also be nice to show some stats there, like how many things still need to be reviewed. It would also be good to do some filtering and sorting
• the ReviewAspect model is used to say how reviews are done. You can set up different scoring mechanisms. Eg rate the Title out of 5, rate the relevance out of 3, etc
• When a Reviewer reviews a talk, we generate a form based on the ReviewAspects that were set up
• People should be able to edit their reviews as well

This PR will not include functionality around making final selections. It's just for the reviewers

Line 8, you forgot the rest two " on the docstring 🙂

When creating a new proposal on create_proposal view, the forms module is getting overridden by django's forms it's not using .forms 🙂
