Guy Sartorelli e374c93ae3 NEW Extend new AbstractGridFieldComponent class 
This makes the `GridFieldSortableRows` component `Injectable`, and
allows any future enhancements in the new abstract class to
automatically apply without requiring additional changes in this module.

The class is introduced in silverstripe/framework 4.11.0 so the
dependency constraint needs to be updated.
