JSONBuilder (#1865)

* #include an absolute path didn't work - because paths were taken to always be relative.

* WIP JSONWriter/JSONParser.

* Checking different Layout styles for JSON.

* Add slang-json-parser.h/.cpp

* WIP JSONValue.

* Added JSONValue::destroy/Recursive.

* Improvement to JSONValue.

* Improve text double conversion precision. Testing.

* Simplify double parsing (just use atof).
JSON comparison
More testing of conversions and start of JSONValue.

* Add <math.h> for isnan, isinf etc.

* Small improvement with object comparison.

* Fix typo in getArgsByName.

* Removed use of isnan and isinf as includes don't work on linux.

* Improve JSON unit test.

* Added asInteger/asFloat/asBool to JSONValue.

* Add SourceLoc to JSONListener.

* Added ability to walk the JSONValue

* JSONBuilder.

* Add converting from lexemes via JSONBuilder.

* Fix VS warning.

* Fix warning for res not being used.
