Title: Use `Meta.abstract`, not `is_abstract`

Page registration in the Page Metaclass now uses `Meta.abstract` over `is_abstract`.

`is_abstract` is non-standard, and replaces existing Django functionality. Infact, all classes in Wagtail code where `is_abstract` is defined also include the `Meta.abstract` flag.
