Added logic for Group Message Requests
Added a 'ManualResultJob' which allows for a way to add a dependency to a job which can be resolved separately from the job system (it's not persistent though)
Added the ability for admins to delete select messages from updated groups
Swapped 'save'/'saved' calls to be 'upsert'/'upserted' as that's the actual behaviour we expect (unique key based rather than primary key based)
Fixed a bug where the 'limitedReuse' 'drainBehaviour' could get stuck in an invalid state
Fixed a bug where job dependencies could swap queues which could theoretically result in deadlocks in some cases
Got a number of the GroupUpdate messages working properly
Updated the DisplayPictureDownloadJob to support OpenGroup room images
Updated the Poller to process messages by namespace (sorted) and added support for synchronous handling of messages
Reworked the ProfileManager to be a more reusable DisplayPictureManager
Cleaned up the conversion from milliseconds to TimeInterval (which is documented as seconds) for clarity
Fixed a read/write crash due to the SnodeAPI cache setup
Fixed an issue where dependencies could incorrectly overwrite each other when based on protocols
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
Fixed a bug where the LinkPreviewView wouldn't render correctly in dark mode
Added migrations for contacts and started working through thread migration (have contact and closed group threads migrating)
Deprecated usage of ECKeyPair in the migrations (want to be able to remove Curve25519Kit in the future)
