Updating Podfile.lock to new AFNetworking version
Refactoring and bug fixing

Changed HYD prefix to SYN
Added proper handling long messages (workaround for AsyncSocket not
handling properly terminal character in longer messages)
Refactoring

Changed to camelCase where needed (since_id, since_time, api_key)
Added SyncServerDelegate protocol

Added protocol to allow opening connection without passing all the
callback parameters. Delegate and callbacks can be used together,
messages will passed to both of them.
