- Using same clang format file for old and new files.
- Moving out all TextSecure code to allow other clients (OS X, iOS) to
integrate easily TextSecure functionality.
- Use TextSecure API to signup.
Implemented using corbett's suggestion in issue #525. Uses
Flipboard/FLAnimatedImage in an AttachmentAdapter. Detects gifs using
new Animated category in MIMETypeUtil.
Backwards compatible with previous versions of Signal on iOS for both
sending and receiving Gifs, though they are sent/received in older
versions as UIImage and won't animate. Gifs also animate on both ends of
conversations with TextSecure users on Android.
