Body processor

This driver accept an optional body processor. First usecase was to convert the body to utf-8 for website not serving unicode.

DSL is a bit different from other x-ray drivers mainly to avoid conflict between driver options and request engine options.

var xray = require('x-ray'),
	request = require('./index.js'),
	Iconv  = require('iconv').Iconv;
	
	var iconv = new Iconv('Windows-1252', 'UTF-8');
	
	var driver = request({
		requestOptions: {
			encoding: null,
		},
		bodyProcessor: function(body, callback) {
			callback(iconv.convert(body).toString());
		}
	});
	
xray('http://example.com/non-utf-8-page')
	.select({
		title: 'h1'
	})
	.use(driver)
	.run(function(err, object) {
		if (err) {
			throw err;
		}

		console.log(object);
	});
