spinOnce is blocking and isReadyReceive is protected

[GoogleCodeExporter]

The spinOnce method of MessageManager is blocking if no messages are currently 
available to process.  Since the purpose of such a method is generally to run 
in realtime critical time slices, such behavior probably needs to be 
redesigned.  A useful workaround seems to be preceding the call with a 
"if(connection.isReadyReceive(0))".  However, calling this explicitly under the 
current code base is impossible since the method is protected.  In my code, I 
have modified the call to be public.

Good catch.  You change seems appropriate (making that function public won't 
hurt anything).  Could you please update the header file comment to reflect the 
actual behavior of the function (i.e. non blocking when zero is passed, it 
currently says the opposite).
