Possibility to hide ParentID dropdown

[wernerkrauss]

If i wanted to decide the Parent of my page using some dropdowns (e.g. category, subcategory) and calculate the ParentID onBeforeWrite i need a possibility to disable the ParentID field CatalogPageExtension is providing.

Should be defined in config yml when extending the pagetype. Of course the i have then the full responsibility of creating the right ParentID.

Great idea - we can config it out although its hard to do a false value through YML at the moment, even the ones we have provided don't seem to work and you have instantiate them through the php layer
