Acceptance of applications from the API website to AMO

Hello!

There is a small written integration, the main Django Framework.

Now you need to add a module for processing applications from the site. At the moment, all forms of feedback come to the mail, but as practice has shown, mail is a very unstable channel with a long delay.

What you need to do
1. Add several methods to accept applications from the API site.
2. Add a duplicate verification algorithm for contact and contact transaction.
