Fixed a bug where returning from the background on the conversation screen would result in the input view being hidden
Refactored the PhotoCollectionPickerViewController to use the SettingsTableViewController convention
Updated the SettingsTableViewModel to worked based on Combine instead of the DatabaseObservable so it's more reusable for non-db cases
Created the ThemeManager and the system to control the dynamic theming
Started updating the main settings screens
Added the AppearanceViewController and connected it to the ThemeManager
Started adding theme values
Started applying theme values throughout
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
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
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)
Removed the 'presentTimer' logic from the 'ModalActivityIndicatorViewController' (the delay looked buggy, if it does have "blipping" issues then we can fix those separately)
