Adding pretty-print support to JSONGenerator.
Fixing a bug where escaped characters would make their way into parsed
string data. Actually, this is only a partial fix, and doesn't cover the
gamut of escape sequences. It does, however, fix single-character
escapes.
Adding a couple of additional tests to confirm that escape sequences are
properly parsed and generated.
Fixing a bug where negative decimal values would be downgraded to integers when reporting to the parser's event listener.
