Auto-reconnect

[dehnert]

AFAICT, if an exception occurs in a backend (eg, a timeout), that backend stops working. It should probably reconnect automatically, or at least have an option to do so.

Okay, it looks like Roost and IRCCloud both support explicit reconnect. It might make sense to give SnipeBackend a reconnect() method that's a no-op (assuming this isn't generalizable, which I think is likely), give the Zulip backend a useful reconnect method, and add a reconnect-all keybinding. I can work on doing that.

yeah, an explicit reconnect function would be useful..

I can work on doing that.

I got hosed (and distracted by #55) so didn't make appreciable progress on this, unfortunately.
