Renamed the 'Legacy' classes to have their library prefix (avoid confusion)
Removed the legacy Objective C Thread code (pulled only the NSCoding stuff into the 'SMKLegacy' type)
Removed some more legacy code
Added back logic similar to the pre-processing de-duping logic (was resulting in "unsent" messages reappearing)
Added a number of updated view files
Fixed a couple of issues around the duplicate messages handling
Fixed a few issues with ClosedGroup polling and ClosedGroup control message handling
Started working through updating the MediaGallery
Tested and fixed a couple of issues with the disappearingMessages job
Added a simple dependency system for jobs (primarily for the AttachmentUploadJob, but will likely be others later)
Setup the AttachmentUploadJob again (looks like there are cases which use it)
Prevented a possible infinite job deferral loop from causing the app to crash (the loop is still technically possible but the app will continue to run now)
Updated the interactions unique constraints based on testing and discussions around how the serverHash works
Deleted the legacy ReadReceipt handling (now managed via the 'interaction.wasRead' flag and 'SendReadReceiptsJob')
Deleted the unused SSKIncrementingIdFinder
Moved the JobRunner into SessionUtilitiesKit so it can be used by SessionSnodeKit
Exposed a 'sharedLokiProject' value on UserDefaults to remove the hard-coded group name used everywhere
Added "blocking" job support for 'OnLaunch' and 'OnActive' jobs to the JobRunner (will retry until it succeeds)
Added the UpdateProfilePicture and RetrieveDefaultOpenGroupRooms jobs
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
Changed the min OS version to iOS 13.0 (support for 'Identifiable')
Removed the alternate approaches to fetching the userKeyPair and userPublicKeyHexString (no consistently routed through the caching method)
Migrated the 'OWSIdentityManager' logic to use the new 'Identity' type
Added the 'Setting' table and got the pattern working fairly nicely (unfortunately there isn't a good way to avoid key collision without proper enums)
Updated the SessionSnodeKit to migration it's data from YDB to GRDB
Updated the SessionSnodeKit to use GRDB throughout it's logic
