Clang Static Analyzer warnings

[andypotion]

Hey John,

It turns out that JSONKit doesn't have difficult to get around clang warnings. According to the benchmarks I ran, the changes here slows down the parsing by an extremely tiny amount, so no worries if you don't want to merge it into the mainline.

Andy,

Thanks for taking the time to look in to this.

However, I've decided to take the position that code should not be modified for the benefit of the static analyzer. At the time version 1.3 was checked in, the version of clang used to perform static analysis reported were all "false positives" and not actual problems.

In this particular case, and IMHO, I'm of the opinion that if there's a "problem", it's with clang, and not JSONKit.
