Update to InputfieldSelector to correct issue with @fields not being populated properly when saved and populated later.
Add FieldtypePageTable / InputfieldPageTable modules to core along with updates to both of those modules and ProcessPageAdd for automatic page adding support.
Update to support subselectors in selector strings. These can be used on the 'id' property of any field that maps to a page. It can also be used on the 'parent' property. Subselectors are specified between [square brackets]. Example: $pages->find("template=product, categories.id=[title%=electronics, active=1, include=hidden], include=all");
