- Extracted autoupdate code from consumers
- collect autoupdates until a AUTOUPDATE_DELAY is reached (since the first autoupdate)
- Added the AUTOUPDATE_DELAY parameter in the settings.py
- moved some autoupdate code to utils/autoupdate
- moved core/websocket to utils/websocket_client_messages
- add the autoupdate in the response (there are some todos left)
- do not send autoupdates on error (4xx, 5xx)
- the client blindly injects the autoupdate in the response
- removed the unused autoupdate on/off feature
- the clients sends now the maxChangeId (instead of maxChangeId+1) on connection
- the server accepts this.
- Added settings.py docs
- Fixed left-overs from #4920
- Reworked all server messages to a new argument formet, so that the
client can translate server messages
