TRUE/FALSE should be booleans not strings

Hi! First, awesome tool. Love it.

A big improvement (IMO) would be native conversion of TRUE and FALSE (case-insensitive) to the lowercase, unquoted true/false JSON equivalents. Currently, they are outputted as strings, which is somewhat counterintuitive since numbers are outputted as numbers and not stringified ones.

I agree this is much needed. Thanks.
