Form Generation Library

Found a bug in Form->submit() and Form->reset(), maybe Form->button(), either.
First, I change this line to enable error message even if el['name'] cannot be found by _el_get_unique($name)

+            $this->error_string .= $this->error_open.$message.$this->error_close;
         }        
         return $this;

So the problem is triggered only when I bypass the nameid parameters for submit(), reset() and button(). It is because Form Generation didn't record the status of this field, because it did not know the name or id of these field.
In the form, I still found <input type='submit' name='Submit' id='submit'> when I run $form->submit('Submit'), but when I submit, the same form appears, like nothing happens at all.
This patch will just help fix submit() and reset().
