Updated to the latest version of GRDB
Fixed an issue with db reentrant behaviour with the Attachment upload function
Finished up the updated 'sendNonDurability' functions
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
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)
Removed the legacy Theme code (replaced with SessionUIKit equivalents)
Removed the OWSOrphanDataCleaner (unused)
Removed the OWSReceiptType_Delivery from the OWSOutgoingReceiptManager (unused)
Removed the TSStorageKeys and TSStorageHeaders files (unused)
Removed the LKMessageIDCollection (unused - only had methods for deleting data from the collection)
Removed the OWSPrimaryStorageTrustedKeysCollection and OWSIdentityManager_QueuedVerificationStateSyncMessages (unused)
Removed collections and notifications from OWSProfileManager (unused)
Updated the migrations so they can specify whether a configuration sync is required
Moved the config sync logic into a MessageSender extension (makes far more sense than AppDelegate)
Fixed a bug where the ShareVC was triggering the 'versionMigrationsDidComplete' twice
Removed a couple of imports for files that had been deleted
Fixed an issue where the "block" button would appear in the NoteToSelf swipe menu
Removed the OWSBlockingManager and supporting files
Removed a number of unused classes and methods
Refactored the BlockListUIUtils to Swift
Disabled the attachments and voice message buttons for the first message
Disabled the Disappearing Messages flag for the until the conversation is approved
Fixed a bug where the recipient of a message request could incorrectly get the 'pending approval' state
Refactored some standard auto layout code to use the custom extension code
Fixed a bug where sharing a text file was resulting in the entire contents being put into the message input field
Fixed a bug where sharing from within the app where the app was in dark mode but the device was in light mode would result in buggy UI
Fixed an issue where sharing form Safari without adding comments would result in an invalid message getting sent.
Fixed a crash when sharing plain text from safari.
Fixed a crash when localising 'OK' (key and value can't be the same when using the new extension).
Updated the share extension to load URL previews.
Updated the ThreadPickerVC to send plain text & URLs in the same way they are sent for normal messages.
