obsolete code in page custom layout settings

[Cecilia Vela Gurovic]

in js/customlayout.js line 225 we have
    $('#togglecustomlayoutoptions').hide();

the element '#togglecustomlayoutoptions' used to contain the "Create custom layout" section in page edit screen, so it could be hidden by clicking on the section title.
 The "Create custom layout" is not hidden anymore, and the element '#togglecustomlayoutoptions' was removed from the html.

The call to $('#togglecustomlayoutoptions').hide() should be removed and also check what other code is not used anymore.
