setting & editing  multi-language in an easy way.

I've add a new parameter in the validate function for setting the language.

``` javascript
    var validator = new FormValidator('example_form', [{
        name: 'req',
        display: 'required',    
        rules: 'required'
    }, {
        name: 'alphanumeric',
        rules: 'alpha_numeric'
    }, {
        name: 'password',
        rules: 'required'
    }, {
        name: 'password_confirm',
        display: 'password confirmation',
        rules: 'required|matches[password]'
    }, {
        name: 'email',
        rules: 'valid_email'
    }, {
        name: 'minlength',
        display: 'min length',
        rules: 'min_length[8]'
    }], 'english', function(errors) {
        if (errors.length > 0) {
            // Show the errors
        }
    });

```

a new parameter in the function `english` ->  for setting up english version.

also you can setting up chinese, chinese_zh version, just change by just changing the parameter.
