Got the updated blinding logic working (at least when authenticating a request - still need to deal with message signing and verification)
Storing the server capabilities in the database now so we can correctly blind requests based on them
Renamed the remaining 'v2' functions and classes to just be 'OpenGroup' since there isn't a 'V2' anymore
Cleaned up a few TODOs and functions
Added some new properties to the OpenGroupV2
Moved a number of methods and variables from OpenGroupAPI to OpenGroupManager (anything doing actual logic)
Moved the message signing into the OpenGroupAPI (since that's the only place it happens)
Renamed remaining old model classes to start with 'Legacy' to make clean up easier
Updated the OpenGroupAPI poll method to use the same logic as it previously did to determine if it should retrieve recent messages or messages since the last one
Cleaned up the OnionRequestAPI so we don't need the LegacyOnionRequestAPI
Added requests for the user endpoints
Added deprecated flags to the legacy endpoints and functions
Added some logic to start handling the new poll (batch) response
Started adding unit tests for the OpenGroupAPI functions
Updated the MessageSendJob to support V4 messages (V2 messages will be upgraded to V4 if they get re-encoded)
Renamed the Message+Destination from 'openGroup' & 'openGroupV2' to 'legacyOpenGroup' and 'openGroup'
Started plugging in more of the V4 APIs
Renamed a number of the V2 APIs to start with 'legacy'
Added the MessageRequestsViewController
Added a 'Message Requests' button to the settings screen
Added accept/reject buttons for message requests to the ConversationVC
Added the ability to hide the message request item on the HomeVC (re-appears if you get a new message request)
Added code to handle an edge-case where the message request approval state wouldn't be returned to the sender due to the recipient running an old version of the app
Prevented contacts which aren't associated with an approved thread from appearing when creating a closed group
Disabled notifications for threads which aren't approved
Updated the app notification count to exclude unapproved messages
Updated the app to ignore closed group creation messages if the group has no admins which are approved contacts
Fixed up the keyboard avoidance behaviour in the ConversationVC
Fixed a couple of minor interaction issues which affected some devices
Fixed an issue where the database migrations would run on the 2nd launch when creating a new account (causing odd behaviours)
Added back localized attachment error messages
Fixed an issue where sending an attachment could fail and the screen would be dismissed before the user had a chance to read the error
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).
