remove(result): return result instead of storing it off

[Integralist]

Fixes #70

Summary

Login now returns (Result, error) instead of error, giving callers direct access to the login response. The deprecated LoginResult field and its associated mutex usage have been removed from Conn.

Caller migration

// Before
err := conn.Login(user, pass, "")
code := conn.LoginResult.Code

// After
result, err := conn.Login(user, pass, "")
code := result.Code

Release

- Tag: `git tag -a v0.2.0 -m "Login returns (Result, error); remove deprecated LoginResult field"`
- Push: `git push origin v0.2.0`

@case-fastly did you want me to do the git tag/release? Are you happy with 0.2.0 or would you prefer to keep incrementing the patch 0.1.8 is next iirc
