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
Updated the HomeVC to count the threads with unread messages using the TSMessageRequestGroup instead of using the UnreadDatabaseView
Removed the OWSMessageUtils 'unreadMessageRequestCount' method
Fixed the unread message counting for message requests
Updated the message request banner to indicate the number of message requests with an unread message
Updated the message request banner to automatically disappear if the user has no unread message requests
Renamed a variable for ReadReceipt management to make it a bit more self-documenting (it looked like it would trigger a read receipt to be sent regardless of the setting)
Removed the "Back" text from the back buttons
Removed the inset on the 'Path' settings button so the text remains horizontally centered
Hid the settings button from message request threads
Fixed an issue where the back button would remain visible in a conversation when the search field was visible
Fixed an issue where the tintColor of the conversation search field didn't match the global search field
Fixed an issue where sending an attachment response to a message request wouldn't approve the message request
Updated the size and positioning of the message request 'Clear All' button to match the DM 'Next' button
Updated the message request 'Clear All' button to start visible (so it's visible during the push animation) since that's the most likely state it'll be in
Updated the 'Message Requests' cell to use the pinned background colour
Updated the fallback for contact thread names to be a middle-truncated string (4 characters either side)
Updated the OpenGroup polling to run on a non-main thread
Updated the TSGroupModel to store moderatorIds as well as the adminIds (new endpoint is only going to give diffs)
Updated the BatchRequest to support json, base64 encoded strings and raw bytes for it's body
Replaced the 'lastMessageServerID' methods with 'OpenGroupSequenceNumber' methods (since we have swapped the property over)
Added an alert when banning fails (previously it would fail silently)
Fixed a bug where sent blinded messages were appearing as incoming messages
Fixed a bug where the OpenGroup infoUpdates wasn't getting decoded correctly
Fixed an issue where the ConversationVC wouldn't become the first responder again after the ban alerts disappeared
Fixed an issue where I'd incorrectly used the message 'seqNo' in place of the message server id
Fixed an issue where open group messages were setting their `sentTimestamp` to seconds instead of milliseconds for incoming messages
Fixed a bug where the ConfigurationMessage was getting generated before the contact state was persisted to the database in the message request flow causing odd behaviours (now generating the ConfigurationMessage within the same transaction)
Fixed a bug where sending a message to an existing message request thread once the message requests item has been hidden would show the message requests notification and trigger the section to re-appear on the home screen
Fixed a bug where blocked contacts weren't getting excluded from the contacts list in the configuration message
