Add all fields to Multiple Entries layout (#2106)

## Testing

- Add `add_filter(
'gk/gravityview/view/new/show-all-fields-in-multiple-entries',
'__return_true' );`
- When added, create a new View
- Select a form with many fields (more than are shown in Gravity Forms
"Entries" screen)
- Select the Table layout

## What you should see:
- All fields should appear in the Mulitple Entries tab
- The first field should be linked to the Single Entry

## Items for @mrcasual 

- Name of the filter
- Code review
