Need to fix auto logout.

[RobertSkonieczny]

After a few hours of running the bot Steam randomly logs us out.

We need to improve the flow to detect a logout, log us in and start trading again.

Just some notes

1. On the main accounts logout. We need to make sure that resend the item to get the profile up and running again.
2. On the bot accounts logout. Make sure the main bot resends a trade and it goes back into the event loop.

I will try to tackle this problem at some point in time, but if someone else can tackle the problem that would be greatly appreciated.

Thank you!
