Add all fields to Multiple Entries layout

[zackkatz]

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

@zackkatz, a bit verbose, but what about gk/gravityview/view/configuration/multiple-entries/initialize-with-all-form-fields?

The code looks and works 🆗.

That updated filter name works for me @mrcasual
