Made a tweak to prevent some odd looking keyboard transitions when going to conversation settings
Updated the PagedDatabaseObserver to not call 'onChangeUnsorted' on the main thread (now we can generate the changeset on the background thread so there is less main thread work)
Fixed an issue where the most recently received message from the swarm could be removed from the swarm yet the app would still poll for it, resulting in the swarm always returning the oldest possible messages until the user sends a new one-to-one message
Fixed an issue where the initial scroll offset could be incorrect due to certain message types
Fixed an issue where the title view inside a conversation could jump when pushing to the conversation settings screen
Refactored a couple of ObjC functions to Swift as they were crashing (due to memory allocation?) hopefully this will fix it
Tweaked some DispatchQueue priorities to ensure PagedDatabaseObserver loading is prioritised
Updated buttons to use a standard convention for highlighted states
Updated the new conversation button to follow the new highlighted state convention
Updated the settings screens to have the "rounded group" styling
Added a "loading conversations" label to the Message Requests screen before the conversations load
Removed the legacy UserCell (replaced with the more reusable 'SessionCell')
Renamed a few things to make them more generic and reusable
