Connection to steam silently lost

[truenicoco]

Summary

After a random amount of time, we are disconnected from steam silently

Reproduction Steps

Write a long running python script, let it run for a few days, then notice that:

• incoming events do not come through anymore
• trying to send a message raise an error

Expected Results

When the connection is lost, steam.py should try to reconnect or at least raise a "DisconnectEvent" of some sort.

Actual Results

The connection is silently lost. Trying to send a message yields

I posted some longer logs in #207 (comment) but I think it was in the thread of a different issue?
