Dendrite 0.9.5

Fixes

• The roomserver will now correctly unreject previously rejected events if necessary when reprocessing
• The handling of event soft-failure has been improved on the roomserver input by no longer applying rejection rules and still calculating state before the event if possible
• The federation /state and /state_ids endpoints should now return the correct error code when the state isn't known instead of returning a HTTP 500
• The federation /event should now return outlier events correctly instead of returning a HTTP 500
• A bug in the federation backoff allowing zero intervals has been corrected
• The create-account utility will no longer error if the homeserver URL ends in a trailing slash
• A regression in /sync introduced in 0.9.4 should be fixed
