Use Laravel for bearer token access

[williamjallen]

While looking through the documentation, I discovered that Laravel provides a Request::bearerToken() helper function.

@williamjallen, I am unable to submit with a bearer token even against the master branch in my development environment with both an admin and non-admin user. The test passes locally and in the CI, so I think we can merge. Any objections?

Seems reasonable to me.
