LP1847800 Admin grid filter display, default fields, IDL repairs

* Indicate in the UI when grid filters are applied via URL and offer a
  way for the user to clear the filters.

* When grid filters are applied, use them as the basis for the "Default
  New Record" object which seeds the fm-editor.  In other words, apply
  default values to the fm-editor to match the grid filters.

* Repair some IDL thinkos and add more 'selector' values.
