Adds minor change and 2 properties to enable indented pretty-print JS…

…ON response and to set indentation space count.

Handy for development and easily legible curl json responses in console.
Properties:
	er.rest.format.ERXJSONRestWriter.shouldPrettyPrint=false (set to true to enable)
	er.rest.format.ERXJSONRestWriter.prettyPrintIndent=2 (or your preferred indent)
