Fix for IOS-8018 crash - This version of JSONKit seems to include some archaic workarounds for improving pointer efficiency in objective c. A VERY long comment left by the original developer shows that s/he was very very passionate about using tagged pointers despite their fragile nature. I looked up what I could about them but mainly found recommendations against their use (pretty much at all times, as the specifically voiced against by Apple as well as many pure C folks). The code change here disables their use, but dear god I hope I haven't broken a thousand other things in forcing a default behavior at such a low level. We might want to consider upgrading rest kit!
