Fixes RODEX retrieve all button (#5238)

* Fixes #5061.
* Resolves the client crashing when attempting to retrieve all attachments from mail.
* Mail should not be marked as read after retrieving the attachments from them.
* Converts packets to new struct format.
Thanks to @admkakaroto and @attackjom!
