xcode 6 warnings

[mohan-agadkar]

Nick, we are getting warnings if run on xcode 6.
For
@Property (nonatomic, getter = isExecuting) BOOL executing;
@Property (nonatomic, getter = isFinished) BOOL finished;
@Property (nonatomic, getter = isCancelled) BOOL cancelled;

Warning: Auto property synthesis will not synthesize property 'executing' because it is 'readwrite' but it will be synthesized 'readonly' via another property

I see it too. It is also crashing all of a sudden now:
[RQOperation setExecuting:]: unrecognized selector sent to instance ...
Not sure why crashes just kicked in given the warnings appeared back in Sep. Anyway, fixed locally here by simply changing the names of these internal variables.
