Remote validation executed before addMethod methods

[matthewvalimaki]

In #679 remote validation was moved to be the last validator in the chain. New validators added with jQuery.validator.addMethod() are appended after remote validation. The added methods should either go in front of remote or when validation is executed remote should be the last validation to be called.

Justification for this is quite clear: calling remote is useless if other validations fail.

Makes sense. There's already some code in place that moves the require method to the front. Something equivalent could move the remote method to the back.
