Extend Node Validator to support per-check title + return total number of errors.

validator.js

/*

Usage:

Var Validator = require('path-To-Your/lib/validator'),
    validator = new Validator();

validator.checkField('first_name', 'foo', {
	isNumeric: 'This is not a number',
	contains: 'The value doesn\'t have a 0 in it'
}).isNumeric().contains('0');

validator.getErrors();

// returns:
{ fields: 
   { first_name: [ 'This is not a number', 'The value doesn\'t have a 0 in it' ] }
  total: 2 }

*/

var Validator = require('validator').Validator;

		this._errors.total++;
