Implement GoogleReader-like API #119
Description
The FreshRSS API is a GoogleReader-like API that is widely adopted. For example, it is supported by Reeder iOS app among many other clients.
Since it is also documented in detail it makes sense to implement it as a future replacement to the Fever API. This would allow to manage feeds and tags from the client app, a thing that currently Fever API doesn't permit.
Work is done in the greader branch.
