Added defensive coding to prevent the LinkDeviceVC from crashing when the nav controller doesn't exist
Fixed an issue where the 'Permissions' callbacks were doing UI logic on background threads

Fixed a bug where some dropdown settings wouldn't refresh their UI when returning from an update via a child screen

Added a toast when copying the sessionId or group URL (fixes to the toast UI as well)
Fixed the new conversation screen styling
Fixed the styling of the various attachment screens
Updated the buttons on the attachment screen to behave like the input view buttons

Added a "loading conversations" label to the Message Requests screen before the conversations load
