Fixed the styling of the various attachment screens

Added support for animated profile images (no ability to crop/resize)
Updated the message trimming to only remove messages if the open group has 2000 messages or more
Updated the message trimming setting to default to be on
Updated the ContextMenu to fade out the snapshot as well (looked buggy if the device had even minor lag)
Updated the ProfileManager to delete and re-download invalid avatar images (and updated the conversation screen to reload when avatars complete downloading)

Fixed a bug where the "trim open group messages" toggle was accessing UI off the main thread
Fixed a bug where the "Chats" settings screen had a close button instead of a back button
Fixed a bug where the 'viewsToMove' for the reply UI was inconsistent in some places
Fixed an issue where the ProfileManager was doing all of it's validation (and writing to disk) within the database write closure which would block database writes unnecessarily

Fixed a bug where the avatar image wouldn't appear beside incoming closed group message in some situations cases
Removed an error log that was essentially just spam

Cleaned up some onion request logic (was passing the version info in some cases when not needed)
Moved the push notification notify API call into the PushNotificationAPI class for consistency
Added a setting to control whether open group messages older than 6 months should be pruned
Added some defensive coding to prevent an edge-case which could cause a crash (wasn't filtering out a potential invalid row from the home screen data)
