creating backbone models for the form and the input elements
validation on the model (only works for 'required' yet)
validations for required|regexp_match|min_length|max_length|greater_than|less_then are working now
validation now works for 'is_unique' with a asynchronous call to the server
all client-side validations work with CI-syntax (xept calback_..)
