jquery.remote-validations.js

// The "remote" validation is built in, but I messed around with this to try and get errors to
// show in the validation summary without having to press the "submit" button. As it turns out,
// there was other code I made for a different form that worked without having to recreate
// the "remote" validation functions - setFocusOutvalidation.
