* zulip: Treat unknown errors with a 10-second backoff.
An unknown error (including an unauthorized error) would fall through
with no calls to time.Sleep, resulting in hammering the server as
quickly as possible.
Add a 10-second sleep in the default error case. The heartbeat is
left with no explicit sleep, but all other codepaths now contain one.
* version: Move version information into a separate package.
This will allow it to be accessed by other sections of the code.
* zulip: Use the matterbridge version in the user-agent.

Breaking change for zulip channel configuration.
For zulip the channel configuration will now need to specify also
the topic with /topic:yourtopic.
Example:
[[gateway.inout]]
account="zulip.streamchat"
channel="general/topic:mytopic"
This fixes the incorrect PR #701 which didn't work with multiple
gateways.
