Updated the SharedConfigMessage type to have a TTL of 30 days
Updated the SnodeAPI to have a 'poll' method to be more consistent with the OpenGroupAPI (it also does multiple things now so is cleaner)

Added the 'ValidatableResponse' protocol to standardise SnodeAPI response validation
Added the libSession version to the logs
Fixed an issue where the user profile pic wouldn't get synced correctly due to memory going out of scope

Started fixing broken unit tests
Fixed a bug where notifications could incorrectly appear for messages in the current thread
Fixed a bug where swiping left/right on images in the MediaDetailViewController could load images from other threads
Fixed a bug where the unread count wouldn't appear correctly when opening a conversation
Fixed a bug where the unread count on the conversation cell could get truncated
Fixed a bug where notifications weren't working correctly when the app is in the foreground
Fixed a bug where we weren't clearing the 'received X new messages' count when in the foreground
Fixed a bug where outgoing messages could get marked as read in a very specific case
Updated the "group notification" logic to only apply to Open Groups (and always doing it rather than just in the background)
Added a placeholder person icon when you have a closed group with a single member
Added a couple of indexes to improve the HomeVC database query performance (reduce launch time by ~15% in some cases)
Added a background task to give message sending the chance to complete when sending the app to the background
Removed an unneeded query from the HomeViewModel init (reduce launch time by ~10% in some cases)
Optimised one of the queries used to load the data needed for the conversation screen
Fixed a number of scrolling behaviours in the ConversationVC
Fixed a bug with the PagedDataObserver when observing associated data (multiple associations with a single paged result were broken)
Fixed a bug with the PagedDataObserver where it would trigger updates for new entries even if the user is offset from the latest data

Fixed a bug where outgoing messages were being considered unread

Fixed an issue with the closed group key pair management (wasn't storing keys correctly)
Refactored the OWSSound (now Preferences.Sound)
Added the logic for the AttachmentDownloadJob and enabled jobs to be cascade deleted via interactions
Optimised the HomeViewModel database observation query (fetch specific columns so changes outside those don't trigger updates)
Updated to the latest GRDB (ran into a deadlock which should be fixed in a newer version)
Refactored the AppDelegate from Objective C to Swift
Updated the HomeVC to use GRDB
Refactored a number of the Job types to be driven via GRDB and the new JobRunner
