Option to automatically copy and delete elements in child tables

Option to automatically copy and delete elements in child tables is option set "has parent".

At this time, we can use own DCA snippet to realize this function - maybe we can add this and select with checkbox

$GLOBALS['TL_DCA']['mm_events'] = array
(
    'dca_config'      => array
    (
        'data_provider'  => array
        (
            'default' => array
            (
                'source' => 'mm_events'
            ),

            'mm_event_dates' => array
            (
                'source' => 'mm_event_dates'
            ),
        ),
        'childCondition' => array
        (
....

@discordier: maybe we can just add a checkbox in the configuration of the input mask - there the model is defined as a child table...
