Change RKObjectMapping's propertyMappings accessor method to simply return the internal array, rather than making a full copy on every access.  Several methods of RKObjectMapping itself call it like a regular accessor (to get the count, for example) and it gets called a tremendous number of times during mapping operations.  This saves a lot of memory during those operations, plus alloc/dealloc/retain/release/autorelease overhead.
