Make /api/v1/users/<user> endpoint work with string username too
I've been working with the Beam API recently and part of what I've been doing includes looking up data about users. The API is pretty great in regards to most things, but the /api/v1/users/<user> endpoint is not one of those in regards to the fact you have to use the user ID to look up a user.
Obviously, you can search the API for the user, and then get the ID from that, but it would be really nice if you could make a request to https://beam.pro/api/v1/users/Matt instead of https://beam.pro/api/v1/users/137.
This shouldn't be too difficult to implement, but would make the life of a developer just slightly easier!
