edit.phtml: some columns can't be saved: no event_date input

[lycenok]

we need to add this to the form:

           <li class="field">
                <label class="giftreg" for="event_date"><?php echo $this->__('Event Date') ?></label>
                <input type="date" name="event_date" id="event_date" value="<?php echo $loadedRegistry->getEventDate(); ?>" title="Event Date"/>
            </li>
