Job Applications API Final

The final release of the API (hopefully).

This release differs from the last one by only two small differences:

• application_id is enforced as an integer for GET /applications/<application_id> simply to avoid 500's
• Added a last-minute /applications/exists endpoint per the request of other teammates, to verify whether an application exists given a URL.

Feature Complete API

The API is now feature complete and fully documented in the wiki as well as under the docs folder (which matches the current state of the wiki).

A few notable changes from the previous release:

• Applicants allowed to withdraw
• Certain functionalities have been made more generic (like updating status)
• Applicants are allowed to add interview questions and comments to their applications
• Authentication flow is more robust
