Rewrite remaining activities (#1712)

Browse source 
* Limit type/method visibility in apub code

* Simplify db_queries traits by removing generics

* Simplify delete activity implementation

* Rewrite delete activities

* Implement helper functions for websocket message sending

* When receiving delete reason as empty string, change to none

* Rewrite remaining activities

* Simplify inbox

* Remove struct ActivityCommonFields, derive ActivityFields trait instead

* Community should announce received activities to followers
