[feature] Allow delivery to sharedInboxes where possible (#847)

* update Activity

* add instance-deliver-to-shared-inboxes setting

* update activity version again

* add SharedInboxURI field to accounts

* serdes for endpoints/sharedInbox

* deliver to sharedInbox if one is available

* update tests

* only assign shared inbox if shared domain

* look for shared inbox if currently nil

* go fmt

* finger to get params.RemoteAccountID if necessary

* make comments clearer

* compare dns more consistently

+// Package propertyendpoints contains the implementation for the endpoints
+// property. All applications are strongly encouraged to use the interface
+// instead of this concrete definition. The interfaces allow applications to
+// consume only the types and properties needed and be independent of the
+// go-fed implementation if another alternative implementation is created.
+// This package is code-generated and subject to the same license as the
+// go-fed tool used to generate it.
+//
+// This package is independent of other types' and properties' implementations
+// by having a Manager injected into it to act as a factory for the concrete
+// implementations. The implementations have been generated into their own
+// separate subpackages for each vocabulary.
+//
+// Strongly consider using the interfaces instead of this package.
