[mythtv] MythTV GUI rebuild of current screen

[Klaas de Waal]

Hi,

Thanks for all the feedback! It turns out that you can update the
current screen by calling

emit getParent()->settingsChanged(this);

The getParent() did the trick. This makes it possible to set fields
visible or not and then update the current page. This is now
implemented in the "Card type" page but there is at least one more
page with a similar problem. To be continued.

Thanks,
Klaas.
