Server: Games API

[RARM]

Ensure the following game API works:

• Upload a game.
• List games.
• Purchase a game (link a game with a user).
• Download a game (verifying that the user owns the game).

Please, double-check the endpoint works (e.g., use curl to test all endpoints). Create some automated tests (this will help with any changes along the way in the coming days).

This Django app works along with the users' app. The latter must work before implementing this app.

The issue uploading games has been solved. I still have to fix some CSRF issue with the other game APIs. I am working on it, but I have a temp solution.

The upload, list, and download APIs are working. I am now moving to focus on the client and leaving other game APIs to @HunterBresler.

Here is some brief documentation on the Games API.
