Added bitcode support.

Fixed casing of property "sessionID" of LSConnectionDetails as "sessionId", for coherence with other Unified Client APIs.

Event client:didChangeProperty: now reports correct iOS client property names, e.g. "pollingTimeout" instead of "pollingMillis".

Fixed potential exception which could be thrown when setting or updating fields and/or items list if logging is enabled at DEBUG level.

Prevented reconnection attempts upon wrong answers from the Server.

Fixed an error in the log of the keepalive interval setting.

Fixed the documentation of client:didReceiveServerError:withMessage: and client:didChangeStatus:, to specify that the former is always preceded, not followed, by the latter with DISCONNECTED.

Changed the type and behavior of connectTimeout. This setting is now represented as a String in order to accept the "auto" value. If "auto" is specified the value used internally will be chosen (and possibly changed over time) by the library itself. Note that "auto" is also the new default value. To check and or modify the current value a property is exposed: currentConnectTimeout. COMPATIBILITY NOTE: if the connectTimeout property is changed by the client code, the given parameter must be modified to be a String. If the connectTimeout property is accesses by the client code its receiving variable must be converted to an NSString; moreover it is likely that connectTimeout accesses should be replaced by currentConnectTimeout ones. See the docs for further details.

Introduced as an improved alternative to the SDK for iOS clients. The interface offered is completely different, and it is very similar to the one currently exposed by the SDK for JavaScript Clients.
