Store user token in cookies
Rationale for this is to implement "single sign-on" between pleroma-fe and admin-fe.
When pleroma-fe and admin-fe are located under the same domain both apps would be able to read cookie named User-Token
and use it to sign in.
If this will be merged I will first implement it in admin-fe, and then here (i.e. ability to sign in to pleroma-fe if user already signed in to admin-fe).
