Taiga integration for Zulip.
Tips for notification output:
*Emojis*: most of the events have specific emojis e.g.
- :notebook: - change of subject/name/description
- :chart_with_upwards_trend: - change of status
etc. If no there's no meaningful emoji for certain event, the defaults are used:
- :thought_balloon: - event connected to commenting
- :busts_in_silhouette: - event connected to a certain user
- :package: - all other events connected to user story
- :calendar: - all other events connected to milestones
- :clipboard: - all other events connected to tasks
- :bulb: - all other events connected to issues
*Text formatting*: if there has been a change of a property, the new value should always be in bold; otherwise the
subject of US/task should be in bold.
