Added base entity Share

 ## [unreleased]
 
+### Added
+* Added base entity `Share` which maps to a `DiasporaReshare` for the Diaspora protocol. ([related issue](https://github.com/jaywink/federation/issues/94))
+
+  The `Share` entity supports all the properties that a Diaspora reshare does. Additionally two other properties are supported: `raw_content` and `entity_type`. The former can be used for a "quoted share" case where the sharer adds their own note to the share. The latter can be used to reference the type of object that was shared, to help the receiver, if it is not sharing a `Post` entity. The value must be a base entity class name.
+
 ### Fixed
 * Converting base entity `Profile` to `DiasporaProfile` for outbound sending missed two attributes, `image_urls` and `tag_list`. Those are now included so that the values transfer into the built payload.

    * Retraction
    * StatusMessage
    * Contact
+   * Reshare
 
 Implementation unfortunately currently requires knowledge of how Diaspora discovery works as the implementer has to implement all the necessary views correctly (even though this library provides document generators). However, the magic envelope, signature and entity building is all abstracted inside the library.
