Removed Vanilla Form Submission

On google chrome, using vanilla html forms, eg:
	document.getElementById("Form_id").submit();
does not properly set the CSRF header from the cookies.
This results in 403 unauthorized errors in chrome when doing certain things.

This is possibly an issue to do with how chrome handles iframes differently from firefox.

To fix, we replaced basic forms with serialized XMLHttpRequests,
which are more common in this codebase anyway.
