wrapError not compatible with jQuery's passed arguments

[shesek]

When jQuery calls the error callback, is passes three arguments - error(jqXHR, textStatus, errorThrown). wrapError only uses the first argument (treating it as resp, which is somewhat wrong as its not the response, its an jQuery XMLHttpRequest-compatible object), making textStatus and errorThrown inaccessible.

Zepto passes two arguments - xhr and status, which is also not compatible with wrapError.

The simplest solution that won't break backward compatibility and work with both jQuery and Zepto would be to just pass everything after the first argument as additional arguments to the wrapped onError, something like:

onError.apply(null, [model, resp, options].concat(Array.prototype.slice.call(arguments, 1)))

Than one would use function(model, jqXHR, options, textStatus, errorThrown) to access everything.

I believe that we pass the complete response object now, to wrapError ... you should be able to access everything you need.
