Login via one-liner

[Nemesis77swe]

Summary

Give user the possibility to pass along the username and password with the "one-liner" command function..

One paragraph explanation of the feature.

Motivation

The reason for this is to simplify batch/script function to send messages.

Why are we doing this? What use cases does it support? What is the expected outcome?

When running a server, and want to use the chat to send information about the server.

Then messenger is requiring Username and password, since the server is often running under another user on Linux, so no login token would exist for that user, which in turn makes Facebook refuse login of the app.

I've been struggling with the for over 24 hours now, and I just realized this issue is causing the errors for my scripts
