Not a huge change, but when it comes to regular expressions, every bit of simplification helps—at least when it comes to readability, if not performance.

I realized after merging #11 that the regular expression at the end of stripJsonComments() would affect quoted strings. The new "stripJsonComments > doesn't modify > strings including trailing commas" test case confirmed this. The new algorithm took a bit of trial and error, and the existing tests really helped distill it to its essence. Quite happy with how it turned out. Also reorganized the test cases with more `describe` blocks. Added the new "maintains correct syntax error position info when..." suite to confirm positional info in JSON.parse errors remains correct.
